Serial Communications Interface Module (SCI)
SCR2–SCR0 — SCI Baud Rate Select Bits
Use this formula to calculate the SCI baud rate:
where:
Table 13-7
for an f
178
These read/write bits select the SCI baud rate divisor as shown in
SCR2–SCR0.
f
PD = prescaler divisor
BD = baud rate divisor
OP
= internal operating frequency
OP
of 7.3728 MHz and the CGM set for an f
shows the SCI baud rates that can be generated with a 4.9152-MHz crystal with the CGM set
