Communication Processor Module
16.7.5.3 SERIAL INTERFACE CLOCK ROUTE REGISTER. The 32-bit, read/write,
memory-mapped serial interface clock route (SICR) register is used to define the universal
serial bus and serial communication controller clock sources that can be one of the four
baud rate generators or an input from a bank of clock pins.
Bits 0–7—Reserved
These bits are reserved and must be set to 0.
