Serial Interface with Time Slot Assigner
7.8.5.3 SI CLOCK ROUTE REGISTER (SICR). The 32-bit SICR is used to define the SCC
clock sources. The clock source can be one of the four baud rate generators or an input from
a bank of clock pins. The SICR appears to the user as a memory-mapped, read-write reg-
ister and is cleared at reset.
GRx—Grant Support of SCCx
SCx—SCCx Connection
RxCS—Receive Clock Source for SCCx
These bits are ignored when the SCCx is connected to the TSA (SCx = 1).
