TIMER2—WAKE-UP TIMER
Timer2 is a 32-bit wake-up up/down counter timer, with a pro-
grammable 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, the 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. When the core is operating at 20.48 MHz and
at CD = 0 with a prescaler of 1, a minimum resolution of 48.83 ns
results.
The counter can be formatted as a plain 32-bit value or as time
expressed as hours:minutes:seconds:hundredths.
Timer2 reloads the value from T2LD when Timer2 overflows.
The Timer2 interface consists of four MMRS: T2LD, T2VAL,
T2CLRI, and T2CON. T2LD and T2VAL are 32-bit registers
and hold 32-bit unsigned integers. T2VAL is a read only
register. T2CLRI is an 8-bit register. Writing any value to this
register clears the Timer2 interrupt. T2CON is a configuration
MMR and is described in Table 55.

Timer2 Load Register
Name: T2LD
Address: 0xFFFF0340
Default Value: 0x00000000
Access: Read/write
Function: This 32-bit register holds the 32-bit value that is
loaded into the counter.
Timer2 Clear Register
