Caution:
Caution:
In COMPARATOR COUNTER mode, the timer counts output transitions from an analog
comparator output. The timer takes its input from the output of the comparator. The TPOL
bit in the Timer Control 1 Register selects whether the count occurs on the rising edge or
the falling edge of the comparator output signal. The prescaler is disabled in the COM-
PARATOR COUNTER mode.
After reaching the Reload value stored in the timer reload high and low byte registers, the
timer generates an interrupt. The count value in the timer high and low byte registers is
reset to
If the timer output alternate function is enabled, the timer output pin changes state (from
Low to High or High to Low) at timer Reload.
Observe the following steps to configure a timer for COUNTER and COMPARATOR
COUNTER modes and initiate the count:
1. Write to the timer control registers to:
2. Write to the timer reload high and low byte registers to set the starting count value.
3. Write to the timer reload high and low byte registers to set the Reload value.
4. Enable the timer interrupt, if appropriate and set the timer interrupt priority by writing
5. Configure the associated GPIO port pin for the timer input alternate function
6. When using the timer output function, configure the associated GPIO port pin for the
7. Write to the Timer Control 1 Register to enable the timer.

The input frequency of the timer input signal must not exceed one-fourth the sys-
tem clock frequency.
The frequency of the comparator output signal must not exceed one-fourth the
system clock frequency.

This affects only the first pass in the COUNTER modes. After the first timer Reload,

Disable the timer
Configure the timer for COUNTER or COMPARATOR COUNTER mode
Select either the rising edge or falling edge of the timer input or comparator output
signal for the count. This selection also sets the initial logic level (High or Low)
for the timer output alternate function. However, the timer output function does
not require enabling.
