IDFSL3: The new DFCT detection is output.
When IDFSL3 = 0, only DFCT in §5-9 is detected and the signal is output from the DFCT pin.
(default)
When IDFSL3 = 1, DFCT in §5-9 and new DFCT are switched and the resulting signal is
output from the DFCT pin.
The timing for switching is as follows;
When DFCT in §5-9 = low, the new DFCT signal is output from the DFCT pin.
When DFCT in §5-9 = high, DFCT in $5-9 is output from the DFCT pin.
After DFCT in §5-9 is switched to low, the time when the new DFCT output is enabled can be
set. (See IDFT1 and IDFT0 of $34E.)

IDFSL2: The new DFCT detection time is set.
After the new DFCT is detected, DFCT=high is held for a specific time. This time is set.
When IDFSL2 = 0, long hold time. (default)
When IDFSL2 = 1, short hold time.
IDFSL1: The new DFCT detection sensitivity is set.
When IDFSL1 = 0, high detection sensitivity. (default)
When IDFSL1 = 1, low detection sensitivity.
IDFSL0: The new DFCT cancel sensitivity is set.
When IDFSL0 = 0, high cancel sensitivity is set. (default)
When IDFSL0 = 1, low cancel sensitivity is set.
IDFT1, 0: After DFCT in §5-9 is switched to low, the time when the new DFCT output is enabled (output
prohibit time) is set.
