Timer2 - Wake-Up Timer
Timer2 is a 32-bit wake-up timer, count-down or count-up,
with a programmable prescaler. It is clocked directly by the
bit unsigned integers. T1VAL and T1CAP are read-only.

Event Select bit:
Set by user to enable time capture of an event
Cleared by user to disable time capture of an event
Event select range, 0 to 31
The events are as described in Table 58. All events are offset by 2, i.e. event 2 in Table 58 becomes event zero for the
purposes of timer 1.

32-bit Up/Down Counter
- T1CON is the configuration MMR described in Table 61
internal 32.768kHz oscillator. The wake-up timer will continue
to run when the core clock is disabled. The clock source can be
scaled by a factor of 1, 16, 256 or 32768.
