6. Write to the Timer Control Register to enable the timer and initiate counting.
In CONTINUOUS Mode, the system clock always provides the timer input. The timer
period is computed via the following equation:
If an initial starting value other than
registers, use the ONE-SHOT Mode equation to determine the first time-out period.
COUNTER Mode
In COUNTER Mode, the timer counts input transitions from a GPIO port pin. The timer
input is taken from the GPIO port pin Timer Input alternate function. The TPOL bit in the
Timer Control 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.
Upon 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
CONTINUOUS Mode Time-Out Period (s)
The input frequency of the Timer Input signal must not exceed one-fourth the system
clock frequency. Further, the high or low state of the input signal pulse must be no less
than twice the system clock period. A shorter pulse may not be captured.
