1, handheld terminal such as mobile phone only are slave (slave unit) and are used under the normal condition, thus the ID pin of Micro-USB (micro USB) interface 110 generally need not, be vacant state for mobile phone circuit;
2 and the mobile phone power-on default conditions are UART serial ports downloading mode, the mobile phone end main control chip can be waited for the order from the UART mouth, if in the regular hour, do not receive orders, promptly enter the start flow process, so the present invention will be provided with Micro-USB (micro USB) interface 110 default signal when circuit design be the UART signal, and, do not detect at open state under the situation of any peripheral hardware insertion, be set to the UART signal yet.
3, after USB and charger were extracted, the analog switch of mobile phone will switch back the serial ports downloading mode that the UART signal links to each other with the Micro-USB interface.
Based on above-mentioned thinking, the present invention's concrete principle of work embodiment illustrated in fig. 2 is as follows: divide three kinds of functions to realize:
First kind of function, the UART serial ports download function by the UART signal wire: divide the analysis of startup and shutdown two states here.
(1) (is defaulted as A11 and is connected to C11 under the off-mode, A21 is connected to C21, as shown in Figure 2): when mobile phone is pressed the start key, base band main control chip electrification reset, the UART serial ports begins to wait for by the UART serial ports downloads the download command that line transmits from computer, and judgement enters downloading mode or enters the normal boot-strap pattern; If inserting the UART serial ports downloads line and receives UART serial ports download command.
Promptly when the described micro USB interface 110 of described interface detection module 130 detections inserts UART channel transfer equipment, and to produce low level be that 0 second control signal is given described electronic switch module 120, controlling described electronic switch module 120 selects described UART data transmit-receive module 140 to be connected to described micro USB interface 110, mobile phone enters downloading mode, begins to carry out software download or renewal by the UART signal wire UART_TXD and the UART_RXD of UART data transmit-receive module 140; If do not receive UART serial ports download command at the appointed time, mobile phone enters the normal boot-strap pattern, if complete handset program, mobile phone normal boot-strap have been arranged in the mobile phone.
(2) under the open state: the default interface signal configures is the UART signal, inserts if there is UART to download line, can carry out the mobile phone debugging mode.
Second kind, be the USB function: on-off state and above-mentioned first kind basic identical: when the usb data line inserts, the usb data line can be by V_BUS end output 5V high level, produce hardware interrupts, this moment, the SEL end was pulled to high level, promptly was produced as first control signal of high level 1; The A12 that controls the described first single-pole double-throw (SPDT) analog switch 121 is connected to C11, and the A22 that controls the second single-pole double-throw (SPDT) analog switch 122 is connected to the pattern of C21, this moment, usb data transceiver module 150 was communicated with Micro-USB (micro USB) interface 110, after interrupting producing, mobile phone carries out the USB device status recognition, after correctly discerning USB device and being configured to correct status, mobile phone can enter USB charge mode and usb data transmission mode this moment.
The third charger function: on-off state with above-mentioned first kind basic identical: when charger inserts, charger can be by V_BUS end output 5V high level, produce hardware interrupts, this moment, SEL was pulled to high level, promptly was produced as first control signal of high level 1; The A12 that controls the described first single-pole double-throw (SPDT) analog switch 121 is connected to C11, and the A22 that controls the second single-pole double-throw (SPDT) analog switch 122 is connected to the pattern of C21, mobile phone usb data transmission circuit 150 is communicated with described miniature interface 110, after interrupting producing, mobile phone carries out the USB device status recognition, when finding that the usb data line states is not right, in the time of can not being identified as USB, mobile phone judges that charger inserts, and mobile phone enters the charger charge mode.
By realizing three kinds of functions simultaneously with upper type, both saved interface, make cell phone appearance more attractive in appearance, realized function again.Also reduced cost of manufacture simultaneously.
