■ 12bit ADC Control 2 (72H)
SLOT: 12bit ADC data reception method select (Table 44)
0: Register (default)
1: Slot
SLOTNO1-0: 12bit ADC measurement result output slot select (Table 50)
Default: “00” (Slot 5)
PINTE: 12bit ADC for touch screen controller power management (Table 46)
0: Power Down
1: Power Up (default)
PMVREF: Internal reference voltage for touch screen controller power management (Table 46)
0: Power Down (default)
1: Power Up
PINTR: DTPEN bit output enable for pen interrupt
Default: “1” (ON)
When PINTR bit is “1”, pen interrupt is output at DTPEN bit.
PENINT: INTN pin output enable for pen interrupt
Default: “0” (OFF)
When PENINT bit is “1”, pen interrupt is output via INTN pin.
GINT: Slot output enable for pen interrupt
Default: “0” (OFF)
When GINT bit is “1” and AC-link operates, pen interrupt is output at bit 0 of slot 12 on SDATAIN.
