SCP1 and SCP0 — ESCI Baud Rate Register Prescaler Bits
SCR2–SCR0 — ESCI Baud Rate Select Bits
13.8.8 ESCI Prescaler Register
The ESCI prescaler register (SCPSC) together with the ESCI baud rate register selects the baud rate for
both the receiver and the transmitter.
Freescale Semiconductor
These read/write bits select the baud rate register prescaler divisor as shown in
These read/write bits select the ESCI baud rate divisor as shown in
SCR2–SCR0.

There are two prescalers available to adjust the baud rate — one in the
ESCI baud rate register and one in the ESCI prescaler register.
