Hello.
I want to emulate SPI rom with PIC, to test various things. The original device works as follows - on power up, it is queried and 32 bytes read. I know that we can work with SHIFTOUT do represent PIC as SPI slave, but how to start sequence? i.e. if I just put corresponding SHIFTOUT statement into loop, it will transmit automatically when CS pin will be active and clock signal applied to clock pin?
