17.2.2. Mode 1: 16-bit Counter/Timer with Auto-Reload
The Counter/Timer with Auto-Reload mode sets the TF2 timer overflow flag when the counter/timer register
overflows from 0xFFFF to 0x0000. An interrupt is generated if enabled. On overflow, the 16-bit value held in the
two capture registers (RCAP2H, RCAP2L) is automatically loaded into the counter/timer register and the timer is
restarted.
Counter/Timer with Auto-Reload mode is selected by clearing the CP/RL2 bit. Setting TR2 to logic 1 enables and
starts the timer. Timer 2 can use either the system clock or transitions on an external input pin as its clock source, as
specified by the C/T2 bit. If EXEN2 is set to logic 1, a high-to-low transition on T2EX will also cause Timer 2 to
be reloaded. If EXEN2 is cleared, transitions on T2EX will be ignored.
