Table 103. DAC Control Register 4 Bit Descriptions
Bit Name Description
INTRPT This bit selects the functionality of the ZEROL/INT pin.
0 = Pin functions as a ZEROL flag pin.
1 = Pin functions as an interrupt pin.
ZEROSEL[1:0] These bits control the functionality of the ZEROR pin when the ZEROL/INT pin is used as an interrupt.
00 = Pin functions as a ZEROR flag pin.
01 = Pin functions as a ZEROL flag pin.
10 = Pin is asserted when either the left or right channel is zero.
11 = Pin is asserted when both the left and right channels are zero.
