HI,

in pic MSSP module there is pit called SMP which

When in master mode it will control whether data is sampled when the PICmicro MCU is in the middle of sending its own data or whether the data is sampled when the PICmicro device is at the end of sending its data.

why this strange option in the SPI protocool ..any one knows applications ??


thx
 

Re: SPI- PIC - SMP

It could be for supporting different spi modes, I think they are called 00, 01, 10 and 11 from memory. However I have seen sampling point options on a lot of different stuff so I don't actually think it has to do with the spi protocol.
