Latest Updated:09/29/2006


(Timer)  Are the latch and the timer simultaneously written to during write-in and the timer value read during read-out regardless of whether the timer is in operation or suspended? [2006/09/29]


It depends on the type of timer, as detailed below:

Timer 1 and A:
The timer and latch are written to simultaneously and the timer count value is read.
Timer X:
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.
