The details of each bit are shown below.
The bit is set to the underlined side at POWER ON/RESET.
(1) DFL COMP STOP TYPE (D )
0
When "Stop Enable" is selected for the DIFFERENTIAL COUNTER COMP STOP ENABLE, this bit is used for
selecting the fast stop or slow stop through deceleration.
(the same specification applies to the COMPARATORs1 and 2).
0: Fast stop
1: Slow stop
(2) DFLINT OUTPUT TYPE (D )
1
This bit is used for selecting the DFLINT output type on the DIFFERENTIAL COUNTER.
(the same specification applies to the COMPARATORs1 and 2).
0: Detection of each COMPARATOR is latched, then output (executing the STATUS3 READ resets the latch).
1: Detection of each COMPARATOR is output as it is without latch.
Note: Selecting 1 outputs detection of each COMPARATOR without latch, so reset of this mode with the
STATUS3 READ is not available.
(3) DFLINT LATCH TRIGGER TYPE (D )
2
When "Latch" is selected for the DFLINT output specification, this bit is used for the latch type.
(the same specification applies to the COMPARATORs1 and 2).
0: Level latch (When the detection condition is valid, executing the STATUS3 READ does not change
active state of the DFLINT output).
1: Edge latch
(When the detection condition is valid, executing the STATUS3 READ resets the DFLINT
output).
Note: When through-output is selected for the DFLINT, latch type selection with this bit is disabled.
