Communication Processor Module
16.7.5.5 SERIAL INTERFACE STATUS REGISTER. The 8-bit serial interface status
register (SISTR) lets you know which part of the serial interface RAM is the current-route
RAM. The value of this register is only valid when the corresponding bit in the SICMR is
cleared.
CRORA—Current Route of TDMA Receiver
This bit is valid in the RAM division mode (RDM field in the SIGMR = 01).
CROTA—Current Route of TDMA Transmitter
This bit is valid in the RAM division mode (RDM field in the SIGMR = 01).
Bits 2–7—Reserved
These bits are reserved and must be set to 0.
