Microcomputer Interface
Microcomputer interface is operated with 7 control signals, which are SI(Serial data input), SO(Serial data output),
SCLK (Serial data input clock), WRDY(Write Ready), CS(Chip select), WRQ(Write Request) and DRDY(Data
Ready). All the data is done serial I/O with MSB first. The operating contents are transferred as 8-bit command data
shown below, and the appointed operations are executed.
Write program RAM
Write code for external conditional jump [JCON](at run,reset) :
Write coefficient RAM
Write coefficient RAM
Write offset RAM

1) Writing Program RAM
The writing to program RAM is executed with 7bytes/set at reset. If all the data is transferred, WRDY pin becomes
"L", and if the writing to PRAM is finished, it becomes "H" and next data becomes be able to be input. In case of
writing data with the continuos address, input the data directly(command code and address are not needed). If it's
discontinuous, set WRQ pin "H"
→
"L", and input in the order of command code, address and data.
