16.4.2 CMX SI1 Clock Route Register (CMXSI1CR)
The CMX SI1 clock route register (CMXSI1CR), displayed in Figure 16-8 , defines the connection of SI1
to the clock sources that can be input from the bank of clocks.
Table 16-3 describes CMXSI1CR fields.
16.4.3 CMX SI2 Clock Route Register (CMXSI2CR)
The CMX SI2 clock route register (CMXSI2CR), seen in Figure 16-9 , defines the connection of SI2 to the
clock sources that can be input from the bank of clocks.
