Timer instruction configuration

Time accuracy refers to the time between the moment the processor enables a timer instruction and the moment the processor completes the timed interval.

The processor uses the following information from the timer instruction:

Timer
: The timer control address in the timer area of data storage.
Time Base
: Determines how the timer operates.
Preset
: Specifies the value that the timer must reach before the processor sets the done bit.
Accumulated value
: The number of time increments the instruction has counted. When enabled, the timer updates this value continually.
