Misc. Control - Register 08h
7.8.1
Power Down (PDN) Bit 7
Function:
When set to 1 (default), the entire device enters a low-power state, and the contents of the control regis-
ters is retained. The power-down bit defaults to ‘1’ on power-up and must be disabled before normal op-
eration in Control Port mode can occur. This bit is ignored if CPEN is not set.
7.8.2
Control Port Enable (CPEN) Bit 6
Function:
This bit is set to 0 by default, allowing the device to power-up in Stand-Alone Mode. Control Port Mode
can be accessed by setting this bit to 1. This allows operation of the device to be controlled by the regis-
ters, and the pin definitions will conform to Control Port Mode.
7.8.3
Freeze Controls (Freeze) Bit 5
Function:
When set to 1, this function allows modifications to be made to the registers without the changes taking
effect until FREEZE is set back to 0. To make multiple changes in the Control Port registers take effect
simultaneously, enable the FREEZE bit, make all register changes, then disable the FREEZE bit.
When set to 0 (default), register changes take effect immediately.
7.8.4
Master Clock Divide-by-2 ENABLE (MCLKDIV2) Bit 4
Function:
When set to 1, the MCLKDIV bit enables a circuit which divides the externally applied MCLK signal by 2
prior to all other internal circuitry.
When set to 0 (default), MCLK is unchanged.
7.8.5
Master Clock Divide-by-3 ENABLE (MCLKDIV3) Bit 3
Function:
When set to 1, the MCLKDIV bit enables a circuit that divides the externally applied MCLK signal by 3
prior to all other internal circuitry.
When set to 0 (default), MCLK is unchanged.
