27.4.3.1.2 Timer Clock Source Selection

PIC32A family devices may have one or more Input Capture channels. Each channel can select between one of eight clock sources for its time base by using the CLKSEL[2:0] bits (CCPxCON1[10:8]), as described in Time Base Generator. The module can be set to use the system clock source or clock from CLKGEN12, with Synchronization mode enabled, in the timer. The Input Capture pin (ICx) should be selected for Input Capture operation. It is recommended that the clock source be selected before enabling the module and not be changed during operation.
