In normal mode, an IRQ is generated each time the value of the
counter reaches zero when counting down. It is also generated
each time the counter value reaches full scale when counting
up. An IRQ can be cleared by writing any value to clear the
register of that particular timer (TxCLRI).
When using an asynchronous clock-to-clock timer, the
interrupt in the timer block may take more time to clear
than the time it takes for the code in the interrupt routine to
execute. Ensure that the interrupt signal is cleared before
leaving the interrupt service routine. This can be done by
checking the IRQSTA MMR.
Hour:Minute:Second:1/128 Format
To use the timer in hour:minute:second:hundredths format,
select the 32,768 kHz clock and prescaler of 256. The hun-
dredths field does not represent milliseconds but 1/128 of
a second (256/32,768). The bits representing the hour,
minute, and second are not consecutive in the register.
This arrangement applies to TxLD and TxVAL when using
the hour:minute:second:hundredths format as set in
TxCON[5:4]. See Table 171 for additional details.

Timer0 (RTOS Timer)
Timer0 is a general-purpose, 16-bit timer (count down) with a
programmable prescaler (see Figure 77). The prescaler source is
the core clock frequency (HCLK) and can be scaled by factors
of 1, 16, or 256.
Timer0 can be used to start ADC conversions as shown in the
block diagram in Figure 77.
