Signal and Window Source Selection

The SMT signal and window sources are selected by configuring the SSEL bits in the SMTxSIG register and the WSEL bits in the SMTxWIN register. Refer the tables below for the possible selections.

The polarity of the signal and window sources can be selected using the SPOL and WPOL bits in the SMTxCON0 register.
