3 Timer1/3/5/… (TMR1)

TMR1 is a 16-bit gated timer supporting both synchronous and asynchronous clock signals. When TMR1 is in Asynchronous mode, the timer functions in Sleep mode and can generate an interrupt to wake the microcontroller. The timer also contains a gating function that can hold the current value. The timer can be configured to buffer the counter to prevent corruption when reading/writing the 16-bit value. The data is latched on the low byte.
