transferred to the Latch register.
On a positive edge at input C, the counter value is
Preload Mode: transferred to the Latch register.
The set value is loaded to the counter.
Confirmation is canceled on a negative edge at
EN_LATC. EL_LATC is dominant over EN_LAT_EXT.
The external Latch input is enabled
On a positive edge at the LATCH input, the counter
Capture Mode:
value is transferred to the Latch register.
On a positive edge at the LATCH input, the counter
Preload Mode: value is transferred to the Latch register.
The set value is loaded to the counter.
Confirmation is canceled on a negative edge at
EN_LAT_EXT.
On a positive edge, the counter is initialized to the set value
INV_DIR
Bit = 0: The counting direction is positive, i.e., from left to right.
Bit = 1: The counting direction is negative, i.e., from right to left.
The request is not acknowledged in the status byte
NOTICE:
(S0.4).
The OUF status bit (S0.4) is reset on a positive edge.
On a positive edge, the set value to which the counter is to be set
for an external event is transferred to the process data.
OpMode
0: Capture Mode: The counter is latched by a trigger signal
Preload Mode: The counter is latched by a trigger signal.
1:
The set value is then loaded to the counter.
