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
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.
