INTCLR Register
ADC Interrupt registers: Clear
OFFSET: 0x00000208
INSTANCE 0 ADDRESS: 0x50010208
Write a 1 to a bit in this register to clear the interrupt status associated with that bit.
3 FIFOOVR2 0x0 RW
FIFO 100 percent full interrupt.
FIFOFULLINT = 0x1 - FIFO 100 percent full interrupt.
2 FIFOOVR1 0x0 RW
FIFO 75 percent full interrupt.
FIFO75INT = 0x1 - FIFO 75 percent full interrupt.
1 SCNCMP 0x0 RW
ADC scan complete interrupt.
SCNCMPINT = 0x1 - ADC scan complete interrupt.
0 CNVCMP 0x0 RW
ADC conversion complete interrupt.
CNVCMPINT = 0x1 - ADC conversion complete interrupt.
