12bit ADC is powered down. Touch screen driver switch is
open.
The AK4650 waits for pen touch. 12bit ADC is powered down.
Touch screen driver switch is open (though XP pin is TSVDD
and YN pin is TSVSS).
12bit ADC is always powered up.
After the measurement of XY or XYZ, 12bit ADC is
automatically powered down and the AK4650 waits for pen
touch.
PMVREF bit controls the VREF power-up/down.
