43. Capacitive Touch Sensing Unit (CTSU)
No interrupt is generated even when an overflow occurs. To determine the channel on which the overflow has occurred,
read the measurement result of each channel after measurement is completed (after a measurement end interrupt is
generated).
This flag is cleared when 0 is written after 1 is read by software. This flag is also cleared using the
CTSUCR0.CTSUINIT bit.
CTSUPS Flag (CTSU Mutual Capacitance Status Flag)
This flag indicates whether the measurement is the first or second of two measurements for each channel in mutual
capacitance full scan mode (CTSUCR1.CTSUMD[1:0] bits = 11b).
This flag indicates 0 while measurement is stopped or in other measurement modes.
