Last Updated:03/06/2017

Question:

(Timer)   Are the latch and timer simultaneously written to during write-in and is the timer value read during read-out regardless of whether the timer is in operation or suspended? [2005/03/01]

Answer:

It depends on the type of timer, as detailed below:
Timer 1: The timer and latch are written to simultaneously and the timer count value is read.
Timers 2, 3, 4, X and Y: The user can choose to have the value written only to the latch or to both the timer and the latch using the timer write control bit setting.
