MOTOROLA
SPR1 and SPR0 — SPI Baud Rate Select Bits
Use this formula to calculate the SPI baud rate:
where:
CGMOUT = base clock output of the clock generator module (CGM)
BD = baud rate divisor
Freescale Semiconductor, Inc.
In master mode, these read/write bits select one of four baud rates as
shown in
Reset clears SPR1 and SPR0.
