DAC2x Volume Control: DAC1A (Address 14h) & DAC1B (Address 15h)
The level for each channel of DAC2 output can be adjusted in 0.5 dB increments as dictated by the DAC2
Soft and Zero Cross bits (DAC2_SOFT & DAC2_ZC) from 0 to -127.5 dB. Levels are decoded in unsigned,
as shown in the table below.
Interrupt Mode (Address 16h)
The Interrupt Mode register contains four two-bit codes which correspond to either an Interrupt Status bit or
group of bits as shown below. There are three ways to set the INT pin active in accordance with the interrupt
condition. In the Rising-edge Active Mode, the INT pin becomes active on the arrival of the interrupt condi-
tion. In the Falling-edge Active Mode, the INT pin becomes active on the removal of the interrupt condition.
In Level Active Mode, the INT pin remains active during the interrupt condition .
Interrupt Mask (Address 17h)
These bits are mask bits for the corresponding bits in the
