Abstract
PURPOSE: To provide program development with efficiency by sending the preset content of a specific register to CPU as if it were the memory content, without reference to the memory content when reading data at a specific address on the memory.
CONSTITUTION: In breakpoint setting resister BPR, data concerned with a desired address is set depending upon an instruction. Comparing circuit CMP, connected to BPR and address ADB, compares the data set in BPR with address signals transferred via ADB one after another and when the both agree with each other, a coincidence signal is generated to set control FF (CFF). Register PGR is stored with data to be transferred to CPU instead of a memory. Then, CFF when set through the switching of sultiplexer MPX sends the content of PGR to CPU via MPX, but when it is reset through the operation of switch S, it sends memory data in main memory unit MM to CPU via MPX.
