27.1.6.1 Timer Mode
Timer mode is the basic mode of operation where the SMTxTMR register is used as a 24-bit timer. No data acquisition takes place in this mode. The timer increments as long as the GO bit has been set by software. No SMT window or SMT signal events affect the GO bit. Everything is synchronized to the SMT clock source. When the timer experiences a period match (SMTxTMR = SMTxPR), the SMTxTMR register is reset and the period match interrupt is set. Refer to the figure below.
