TMD3782 – 21

The Clear Channel Interrupt Threshold registers provide 16 bit

values to be used as the high and low thresholds for comparison

to the 16 bit CDATA values. If AIEN (r0x00:b4) is enabled and

CDATA is not between AILT and AIHT for the number of

consecutive samples specified in APERS (r0x0C) an interrupt is

asserted on the interrupt pin.

The Proximity Interrupt Threshold registers provide 16 bit

values to be used as the high and low thresholds for comparison

to the 16 bit PDATA values. If PIEN (r0x00:b5) is enabled and

PDATA is not between PILT and PIHT for the number of

consecutive samples specified in PPERS (r0x0C) an interrupt is

asserted on the interrupt pin.
