This bit defaults to 0, allowing the device to power-up in Stand-Alone mode. The Control port mode
can be accessed by setting this bit to 1. This will allow the operation of the device to be controlled by
the registers and the pin definitions will conform to Control Port Mode. To accomplish a clean power-
up, the user should write this bit within 10 ms following the release of Reset.
This function allows modifications to be made to the registers without the changes taking effect until
the FREEZE is disabled. To make multiple changes in the Control port registers take effect simulta-
neously, enable the FREEZE Bit, make all register changes, then Disable the FREEZE bit.
The MCLKDIV bit enables a circuit which divides the externally applied MCLK signal by 2 prior to all
other internal circuitry.
When enabled the respective DAC channel pair x (AOUTAx and AOUTBx) will remain in a reset state.
It is advised that changes to these bits be made while the power down bit is enabled to eliminate the
possibility of audible artifacts.
