RX23W Group 43. Capacitive Touch Sensing Unit (CTSU)
43.2.4 CTSU Sensor Stabilization Wait Control Register (CTSUSST)
The CTSUSST register should be set when the CTSUCR0.CTSUSTRT bit is 0.
CTSUSST[7:0] Bits (CTSU Sensor Stabilization Wait Control)
These bits set the stabilization wait time for the TSCAP pin voltage. The value of these bits should be fixed to
00010000b. If these bits are not set, the TSCAP voltage becomes unstable at the start of measurement, and the CTSU is
unable to obtain correct touch measurement results.
