Reading the Timer Count Values
Timer Pin Signal Operation

3. Write to the Timer Reload High and Low Byte registers to set the Compare 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. 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:
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 reg-
ister. This operation allows accurate reads of the full 16-bit timer count value while
enabled. When the timers are not enabled, a read from the Timer Low Byte Register
returns the actual value in the counter.
The timer output function is a GPIO port pin alternate function. The Timer Output is tog-
gled every time the counter is reloaded.
