Infrared Serial Communications
13.11.7 SCI Baud Rate Register
Data Sheet
282
Address:
Infrared Serial Communications Interface Module (IRSCI)
The baud rate register selects the baud rate for both the receiver and the
transmitter.
CKS — Baud Clock Input Select
SCP1 and SCP0 — SCI Baud Rate Prescaler Bits
SCR2–SCR0 — SCI Baud Rate Select Bits
Reset:
Read:
Write:
This read/write bit selects the source clock for the baud rate
generator. Reset clears the CKS bit, selecting CGMXCLK.
These read/write bits select the baud rate prescaler divisor as shown
in
These read/write bits select the SCI baud rate divisor as shown in
