generate interrupt, and continue to count.
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
register 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
while 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. Generally, the Timer Output is toggled
every time the counter is reloaded.
A Noise Filter circuit is included which filters noise on a Timer Input signal before the
data is sampled by the block.
