Programmable Registers
38.5.4 LRADC Control Register 3 (HW_LRADC_CTRL3)
The LRADC touch panel control register specifies the voltages at which a touch detect
interrupt is generated.
HW_LRADC_CTRL3: 0x030
HW_LRADC_CTRL3_SET: 0x034
HW_LRADC_CTRL3_CLR: 0x038
HW_LRADC_CTRL3_TOG: 0x03C
The LRADC touch detect control and status register controls the voltage at which a touch
detection interrupt is generated. This register also contains the interrupt request status bit
and enable bit for the touch detection interrupt request to the CPU's IRQ interrupt input.
EXAMPLE
BW_LRADC_CTRL3_HIGH_TIME(BV_LRADC_CTRL3_HIGH_TIME__83NS);
BW_LRADC_CTRL3_INVERT_CLOCK(BV_LRADC_CTRL3_INVERT_CLOCK__NORMAL);
