1. The CHxB-CHxC short circuit switch can be turned ON by the BCSHORT bit in the TSCUCR1 register.
2. The CHxB-CHxC short circuit switch can be turned OFF by the BCSHORT bit in the TSCUCR1 register.
CHxA0 or CHxA1
CHxA0 or CHxA1
Random setting for period 6 (the RANDOM6 bit in the TSCUMR register is 1)
Either the CHxA0 or CHxA1 pin state is indicated for CHxA.
These states are controlled by bits CHXAS00 to CHXAS08, CHXAS10, CHXAS11, CHXAS16 to CHXAS25,
CHXAS27, CHXAS28, and CHXAS31 to CHXAS35 in registers TSCHSEL0 to TCSHSEL2 as follows:
When CHxA0 is selected by the detection pin, CHxA0 is set to low or Hi-Z output by status control and CHxA1
is always set to Hi-Z output.
When CHxA1 is selected by the detection pin, CHxA1 is set to low or Hi-Z output by status control and CHxA0
is always set to Hi-Z output.
The timing of status periods can be adjusted as shown in Figure 25.4.
Turning ON/OFF of PRE measurement can be controlled by the PREMSR bit in the TSCUMR register.
When the PREMSR bit is set to 1 (PRE measurement), the measurement result of PRE measurement is reflected
in the primary counter. When the PREMSR bit is set to 0 (no PRE measurement), the measurement result is not
reflected in the primary counter.
The random measurement function and the majority measurement function are not used in PRE measurement.

measurement
The number of cycles is selected by registers TSCURVR0 to TSCURVR2.
The selected number of cycles depends on the same bit as used for random measurement (1 to 16 cycles).
The number of cycles is selected sequentially by registers TSCURVR0 to TSCURVR2 even when no random
measurement is in progress.
