Pulse/DIR, With Reload, Count Repetitively, DI Gate Enable, Rising Edge Start
Figure 3.42 shows pulse/direction mode, Ch0_A provides the counting function, one
pulse, one count. Ch0_B provides the clockwise and counter clockwise function.
When the counter0 is enabled, the couner0 starts to count. If the counter value is
overflow or underflow, it will reset to the defined value (e.g. 0x33) and keep counting.
If the DI0 status is rising edge, the counter0 will starts to count and won’t be retrig-
gered.

DO Alarm Function No Gate
High Pulse:
the DO original status will be low and when the counter value
counts to defined alarm value, the DO status will change low to high.
Low Pulse:
the DO original status will be high and when the counter value
counts to defined alarm value, the DO status will change high to low.
No Auto Reload:
When the counter is overflow or underflow, the value will be
reset to the initial value but not count again.
Auto Reload:
When the counter is overflow or underflow, the value will be reset
to the initial value and count again.
High Alarm:
when the counter value is greater than the assigned counter alarm
value, the DO will be active.
Low Alarm:
When the counter value is less than the assigned counter alarm
value, the DO will be active.
Because the DI gate is disabled, whatever the DI value is, the counter still continu-
ously counts. When the counter0 value is overflow, the value will be reset to the initial
value like 0x33. Count once means if the counter0 is overflow, it won’t count again.
