TIMER2 OR WAKE-UP TIMER
Timer2 is a 32-bit wake-up timer, count-down or count-up,
with a programmable prescaler. The prescaler is clocked directly
from one of four clock sources, namely, the core clock (which is
the default selection), the low power 32.768 kHz oscillator,
external 32.768 kHz watch crystal, or the precision 32.768 kHz
oscillator. The selected clock source can be scaled by a factor of
1, 16, 256 or 32,768. The wake-up timer continues to run when
the core clock is disabled. This gives a minimum resolution of
48.83 ns when operating at CD zero, the core is operating at
20.48 MHz with a prescaler of 1.
The counter can be formatted as a plain 32-bit value or as
hours:minutes:seconds:hundredths.
Timer2 reloads the value from T2LD when Timer2 overflows.
The Timer2 interface consists of four MMRS.
T2LD and T2VAL are 32-bit registers and hold 32-bit
unsigned integers. T2VAL is read only.
T2CLRI is an 8-bit register. Writing any value to this
register clears the Timer2 interrupt.
T2CON is the configuration MMR described in Table 55.
Description
Format.
00 = binary (default).
01 = reserved.
10 = hours:minutes:seconds:hundredths (23 hours to 0 hours).
11 = hours:minutes:seconds:hundredths (255 hours to 0 hours).
Prescaler.
0000 = source clock/1 (default).
0100 = source clock/16.
1000 = source clock/256.
1111 = source clock/32,768.

T2LD is a 32-bit register that holds the 32-bit
value that is loaded into the counter.

Write only
This 32-bit, write only MMR is written (with
any value) by user code to clear the interrupt.
