Caution:
COMPARATOR COUNTER Mode
In COMPARATOR COUNTER mode, the timer counts input transitions from the analog
comparator output. The TPOL bit in the Timer Control Register selects whether the count
occurs on the rising edge or the falling edge of the comparator output signal. In
COMPARATOR COUNTER mode, the prescaler is disabled.
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
enabled, the Timer Output pin changes state (from Low to High or from High to Low) at
timer Reload.
Follow the steps below for configuring a timer for COMPARATOR COUNTER mode and
initiating the count:
1. Write to the Timer Control register to:
2. Write to the Timer High and Low Byte registers to set the starting count value. This
3. Write to the Timer Reload High and Low Byte registers to set the Reload value.
4. If appropriate, enable the timer interrupt and set the timer interrupt priority by writing
5. If using the Timer Output function, configure the associated GPIO port pin for the
6. Write to the Timer Control register to enable the timer.
In COMPARATOR COUNTER mode, the number of comparator output transitions since
the timer start is given by the following equation:
The frequency of the comparator output signal must not exceed one-fourth the system
clock frequency.

timer Reload in COMPARATOR COUNTER mode, counting always begins at the

Disable the timer.
Configure the timer for COMPARATOR COUNTER mode.
Select either the rising edge or falling edge of the comparator output signal for the
count. This also sets the initial logic level (High or Low) for the Timer Output
alternate function. However, the Timer Output function is not required to be
enabled.
