SCTHRL
This register sets the soft clip threshold level.
When PCM signal with more than of this bit is input, the LSI clips it according to a value of SCGAIN and works.
The value of threshold level is 23bit (SCTHRM [6:0], SCTHRM [7:0], and SCTHRL [7:0])
Please do not change the value of this bit during Soft Clip function movement.
SCGAIN
This sets the magnification during soft clip.

This register controls the touch panel interface, and a light, please do "1" in bit 3.
TCHEN
This enables and disables the touch panel interface. In the case of "0", this bit is cleared after (an automatic mode in the
case of enable), the lead of the AD conversion data of the touch panel interface TCHA2 bit by "0".
TCHEN
Explanation
0x0
A touch panel interface is disabled.
0x1
A touch panel interface is enabled.
TCHA2
It controls the convert mode of the touch panel interface, and, in the case of "1", this bit interrupts it after the lead of the AD
conversion data of the touch panel interface automatically and changes in a mode. The next conversion starts by an
automatic mode leading AD conversion result in the case of disable.
