It is the composition. The functions of this MPU 21 will be explained below in the case of copying name data and telephone number data from the data buffer to the display buffer.

Although the MPU 21 has a 4-bit data bus, it copies from the name data buffer to the dot matrix display buffer! The data is 8 bits. Therefore, this 8
Name data composed of bits is divided into upper 4 bits and lower 4 bits and copied. At this time 4 b
Copying is performed via the accumulator (ACC), which is an it register. This process is illustrated in FIGS. 5(a) and 5(b).

Next, when copying telephone number data to the segment display buffer, since one piece of telephone number data is 4 bits, processing is performed by one copy. This process is illustrated in FIG. 5(c).

Finally, the case of copying a telephone number to the dot matrix display buffer will be explained. In this case, the operation includes converting telephone number data into dot matrix character data. First, copy the phone number data to the accumulator. Next, data conversion is performed on the accumulator to generate 8-bit data, which is dot matrix character data.

Furthermore, the upper 4 bits of the 8-bit data are copied to the dot matrix display buffer via the accumulator (see FIG. 5(d)). and the remaining bottom 4
The bit is copied to the dot matrix display buffer via the accumulator in the same way as above (Fig. 5(e)).

Next, the processing of the MPU 21 will be explained according to the flowchart shown in FIG. This will be explained by taking as an example data entered using a telephone number of 12 digits or more in the telephone directory mode. In the explanation, we will first explain the data structure of names and telephone numbers, then describe the display process without scrolling, and then explain the display process when scrolling.

Data Structure As a data structure, name data has an 8-bit code for each piece of data because it handles alphabets, numbers, and symbols, and telephone number data has a 4-bit code for each piece of data because it handles numbers and symbols. There is.

Display processing when not scrolling Next, display processing without scrolling will be described.

However, for example, “RobertSmit” is stored in RAM20.
It is assumed that Mr. h”'s telephone number is registered along with his name.

The telephone number of Robert S++++ith is called and displayed by the following operation. (Operation: ty temporary + 2 → loeco) When displaying data, the MPU 21 first copies the portion to be displayed in the data buffer (RAM 20) to the display buffer, and displays according to the contents of the display buffer. First, the 12-digit name data is copied to the dot matrix display buffer. At this time, one data is 8 bits. Second, the first 1 of the phone number data
Copy 2 digits to segment display buffer. At this time, l data is 4 bits. Finally, by performing display processing, the name data and number data are displayed on the LCD.
Display on I. The procedure of this process is shown in FIGS. 7(a) to 7(c).

Display processing when scrolling is not performed Next, the display processing when scrolling is performed, which is a feature of this embodiment, will be described.

When referring to data in the third row (in the data buffer) that is not displayed on the LCD II by pressing the [] key 16d, it is determined that the telephone number data is moved to the dot matrix display section 12 in the first row. (Step 3
0). This involves storing a pointer indicating the display range in the data buffer in advance, and then determining whether name data or telephone number data will appear in the first dot matrix display area based on the position indicated by the upstream pointer. I can do it. When it is determined that telephone number data will be displayed on the dot matrix display section through the above processing, telephone number data 4
The bits are converted to 8 bits for dot matrix display (step 31) and copied to the dot matrix display buffer (step 32). In copying to the display buffer, it is determined whether the data is the 12th data (step 33), and if it is not the 12th data, the next telephone number data is called (step 34), and the process returns to step 31. Step 3
In step 3, when the data is the 12th data, that is, when the dot matrix display conversion of the telephone number data in the second row of the data buffer is completed, the telephone number data in the third row of the data buffer is then called (step 35) and segment display is performed. Copy to buffer (step 36). In copying to the display buffer, it is determined whether the telephone number data is the 24th (step 37), and the telephone number data is the 24th.
If it is the fourth, it is assumed that the process has been completed, and by performing display processing, the entire telephone number data is divided into the dot matrix display section 12 and the segment display section I3 and displayed respectively (step 38). If the telephone number data in the third row is less than 24 digits, "spaces" are inserted for the missing digits to make the number of digits 24. Figure 8 (a
) to (c) show the procedure of this process.

Note that if the telephone number data does not arrive in step 30, that is, if it is name data, the name data is copied to the dot matrix display buffer (step 39), and it is determined whether the name data is the 12th name data (step 40).
If it is not the 12th data, the next data is called (step 41) and the process returns to step 39; if it is the 12th data, the process moves to step 35.

(g) Effect of the invention According to this invention, information for dot matrix display can be
Since it can be processed by MPU with bit configuration,
The cost of the MPU can be reduced, and the RAM can be configured with a small storage capacity.Furthermore, according to the present invention, even if the input numerical information exceeds the predetermined number of characters in the segment display section, the numerical information will be displayed as a dot. Since a list is displayed using the matrix display section, numerical information with a large number of digits can be checked and manually entered. Further, even when reading out mathematical information, the numerical information not displayed on the segment display section can be displayed as a list by dividing it into the dot matrix display section and the segment display section, respectively.
