21.1.1 Clock Source Selection
The SMT clock source is selected by configuring the CSEL bits in the SMTxCLK register. The clock source can be prescaled using the PS bits of the SMTxCON0 register. The prescaled clock source is used to clock both the counter and any synchronization logic used by the module. Refer the table below for possible clock source options.
The polarity of the clock source can be selected using the CPOL bit in the SMTxCON0 register.
