CONTINUOUS Mode
In CONTINUOUS mode, the timer counts up to the 16-bit Reload value stored in the
timer reload high and low byte registers. After reaching the Reload value, the timer gener-
ates an interrupt, the count value in the timer high and low byte registers is reset to
and counting resumes. If the timer output alternate function is enabled, the timer output
pin changes state (from Low to High or High to Low) after timer Reload.
Observe the following steps to configure a timer for CONTINUOUS mode and initiate
count:
1. Write to the timer control registers to:
2. Write to the timer high and low byte registers to set the starting count value (usually
3. Write to the timer reload high and low byte registers to set the Reload period.
4. Enable the timer interrupt, if required and set the timer interrupt priority by writing to
5. When using the timer output function, configure the associated GPIO port pin for the
6. Write to the Timer Control 1 Register to enable the timer and initiate counting.
The timer period is calculated by the following equation:
If an initial starting value other than
isters, use the ONE-SHOT mode equation to determine the first timeout period.
COUNTER and COMPARATOR COUNTER Modes
In COUNTER mode, the timer counts input transitions from a GPIO port pin. The timer
input is taken from the associated GPIO port pin. The TPOL bit in the Timer Control 1
Register selects whether the count occurs on the rising edge or the falling edge of the timer
input signal. In COUNTER mode, the prescaler is disabled.

reload in CONTINUOUS mode, counting always begins at the reset value of
the relevant interrupt registers.
