16.7.5.4 SERIAL INTERFACE COMMAND REGISTER. The 8-bit serial interface
command register (SICMR) allows you to dynamically program the serial interface RAM.
The contents of this register are only valid in the RAM division mode. For more information
about dynamic programming, refer to Section 16.7.4.4 Serial Interface RAM Dynamic
Changes.
CSRRA—Change Shadow RAM for TDMA Receiver
When set, this bit causes the serial interface receiver to replace the current route with the
shadow RAM. You set this bit and the serial interface clears it.
CSRTA—Change Shadow RAM for TDMA Transmitter
When set, this bit causes the serial interface transmitter to replace the current route with the
shadow RAM. You set this bit and the serial interface clears it.
Bits 2–7—Reserved
These bits are reserved and must be set to 0.
