SSP in SPI slave mode

SSP in SPI slave mode

2006-02-12 by Gus

I having many difficulties with SSP running in slave SPI mode. Has 
anyone luck with using it in slave SPI mode?

Why you need to set the clock divider (SSPCPSR)in slave mode!!??!!
When I set it to different values I get different outcome but it 
never work right. I can use it in pooled mode no problem but I am 
writing an interrupt driver with 256 bytes for RX and TX.

Any pointers would be appreciated

When master, you define the clock speed but what about slave?
