Freescale Semiconductor
Infrared Serial Communications Interface Module (IRSCI)
Use this formula to calculate the SCI baud rate:
where:

SCI clock source = f
(selected by CKS bit)
PD = prescaler divisor
BD = baud rate divisor
SCR2, SCR1, and SCR0
shows the SCI baud rates that can be generated with a
