Hi

I have another SPI or microwire bus question.

I am also looking at extending the output pin capabilities of my PIC by using
a 74LS595. I have never used a chip like this before and I would like to use
the SPI bus clock and data lines, that I am using to control an SPI eeprom
and DAC, for the SCK and RCK pins of the 74LS595.

I believe I can use the SI pin like a CS(chip select) Is that correct? It
looks like the data isn't clocked in until the SI line is pulsed.

If I keep the SI line low when I don't want data shifted in, will it ignore
the status of the RCK line as the SPI bus is talking with other chips?

Thanks
