Reading the Timer Count Values
Timer Pin Signal Operation
6. Write to the Timer Control Register to enable the timer.
7. Counting begins on the first appropriate transition of the timer input signal. No inter-
In CAPTURE/COMPARE Mode, the elapsed time from timer start to capture event can be
calculated using the following equation:
Capture Elapsed Time (s)
The current count value in the timers can be read while counting (enabled). This capability
has no effect on Timer operation. When the timer is enabled and the Timer High Byte Reg-
ister is read, the contents of the timer low byte register are placed in a holding register. A
subsequent read from the timer low byte register returns the value in the holding register.
This operation allows accurate reads of the full 16-bit timer count value when enabled.
When the timers are not enabled, a read from the timer low byte register returns the actual
value in the counter.
Timer output is a GPIO port pin alternate function. The timer output is toggled every time
the counter is reloaded.
The timer input can be used as a selectable counting source. It shares the same pin as the
complementary timer output. When selected by the GPIO alternate function registers, this
pin functions as a timer input in all modes except for the DUAL PWM OUTPUT Mode.
For this mode, no timer input is available.
