The Auxiliary DAC 1 control register comprises two bytes located at Address 0x06. These bits are routed directly to the periphery of the
digital logic. No digital functionality within the main digital block is required.

0x06
[15]
Auxiliary DAC 1 sign
0: Default. If the Auxiliary DAC 1 sign bit is cleared, the Aux DAC 1 sign is positive.
Pin 90 is the active pin.
1: If the Auxiliary DAC 1 sign bit is set, the Aux DAC 1 sign is negative. Pin 89 is the
active pin.

Auxiliary DAC 1
current direction
0: Default. If the Auxiliary DAC 1 current direction bit is cleared, the Aux DAC 1 sources
current.
1: If the Auxiliary DAC 1 current direction bit is set, the Aux DAC 1 sinks current.
[13]
Auxiliary DAC 1
power-down
0: Default. If the Auxiliary DAC 1 power-down bit is cleared, the Aux DAC 1 is active.
1: If the Auxiliary DAC 1 power-down bit is set, the Aux DAC 1 is inactive and enters a
low power state.

Auxiliary DAC 1 data
These bits are the Auxiliary DAC 1 gain adjustment bits.
The Q DAC control register comprises two bytes located at Address 0x07. These bits are routed directly to the periphery of the digital
logic. No digital functionality within the main digital block is required.

Q DAC sleep
0: Default. If the Q DAC sleep bit is cleared, the Q DAC is active.
1: If the Q DAC sleep bit is set, the Q DAC is inactive and enters a low power state.
[14]
Q DAC power-down
0: Default. If the Q DAC power-down bit is cleared, the Q DAC is active.
1: If the Q DAC power-down bit is set, the Q DAC is inactive and enters a low power state.

Auxiliary DAC 2 sign
0: Default. If the Auxiliary DAC 2 sign bit is cleared, the Aux DAC 2 sign is positive.
Pin 86 is the active pin.
1: If the Auxiliary DAC 2 sign bit is set, the Aux DAC 2 sign is negative. Pin 87 is the
active pin.

Auxiliary DAC 2
current direction
0: Default. If the Auxiliary DAC 2 current direction bit is cleared, the Aux DAC 2 sources
current.
1: If the Auxiliary DAC 2 current direction bit is set, the Aux DAC 2 sinks current.

Auxiliary DAC 2
power-down
0: Default. If the Auxiliary DAC 2 power-down bit is cleared, the Aux DAC 2 is active.
1: If the Auxiliary DAC 2 power-down bit is set, the Aux DAC 2 is inactive and enters
a low power state.
