Use this formula to calculate the SCI baud rate:
where:
Table 12-8
24MHz OSCDCLK (OSCXCLK=12MHz) as SCI clock source.
SCI clock source = OSCDCLK
PD = prescaler divisor
BD = baud rate divisor
Serial Communications Interface Module (SCI)
SCR2, SCR1, and SCR0
shows the SCI baud rates that can be generated with a
