Control bits Notes
CTRL_SYN You use this bit to enable synchronization.
EXTF_ACK Error acknowledgment
The error bits must be acknowledged with the EXTF_ACK control bit after the cause is removed. (see
figure below)
LOAD_PREPARE Load counter preparatory (see figure below)
The value from bytes 0 to 3 is applied as the load value.
LOAD_VAL The value from bytes 0 to 3 is loaded directly as the new count value.
RES_STS Start resetting of status bit
The status bits are reset through the acknowledgment process between the RES_STS bit and the
RES_STS_A bit. (see figure below)
SW GATE The SW gate is opened/closed via the control interface with the SW_GATE bit.
