The DRDY bit is set to “1” in the status of data ready.
When the data ready interrupt is invalid, this bit is fix to “0”.
The TOUCH bit is set to “1” in the status of touch transition.
When touch interrupt is invalid, this bit is fix to “0”. The sense terminal connected
to the interrupt is selected by IRQM register. (Address 0x66~0x67, 0x6A~0x6B,
0x6E~0x6F)
The REL bit is set to “1” in the status of release transaction.
When release interrupt is invalid, this bit is fix to “0”. The sense terminal
connected to the interrupt is selected by IRQM register. (Address 0x66~0x67,
0x6A~0x6B, 0x6E~0x6F)
The ACF bit is set to “1”, when the measured value of the sense terminal is over
the upper limit at the termination of automatic setting. When the automatic setting
or the automatic setting fail interrupt is invalid, this bit is fix to “0”.
The RANGE bit is set to “1”, when the measured value of the sense terminal is
over the upper limit. When the automatic resetting or the range over interrupt is
invalid, the bit is fix to “0”.
The GPIN bit is set to “1” when a GPIO Input Interrupt occurs. When the GPIO
input interrupt is invalid, the bit is fix to “0”.
