In the MC9S12XEP100RMV1.pdf data sheet it gives the formula to calculate the baud rate for SPI.
BaudRateDivisor = (SPPR + 1) * 2(SPR + 1)
Baud Rate = BusClock / BaudRateDivisor
You have to lookup a table to find the SPPR and SPR values. This table is based on a bus of 25 Mhz.
I am using 24 Mhz bus. Where do I find a table for this speed ?
