CTSU Channel Enable Control Register 4 (CTSUCHAC4)
Note 1. TS32, TS33, and TS34 pins are not available.
The CTSUCHAC4 register should be set when the CTSUCR0.CTSUSTRT bit is 0.
CTSUCHAC4j Bit (CTSU Channel Enable Control 4j) (j = 0 to 3)
This bit sets the pin (for receive and transmit) whose electrostatic capacitance is to be measured.
CTSUCHAC40 bit corresponds to TS32 pin and CTSUCHAC43 bit corresponds to TS35 pin.
Note:
TS32, TS33, and TS34 pins are not available.
