27.1.6.8 Capture Mode

This mode captures the SMTxTMR register value based on a rising or falling edge of the SMT_window input and triggers an interrupt. This mimics the capture feature of a CCP module. The timer begins incrementing upon the GO bit being set. The SMTxTMR register value is written to the SMTxCPR register on each rising edge of the SMT_window input. The SMTxTMR register value is written to the SMTxCPW register on each falling edge of the SMT_window input. The timer is not reset by any hardware conditions in this mode and must be reset by software, if desired. Refer to the figures below.
