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.
Popguard Enable (POPG_EN) Bit 4
Function:
When set to 1, (default) the Device will initiate a ramping function as outlined in
When set to 0, the outputs will step to VQ upon release of PDN.
RMCK control (RMCK_CTRL[1:0]) Bits 3:2
Default = 00
Function: These bits set the function of the RMCK pin with respect to the LRCK.
RMCK Ratio Select (R_SELECT[1:0]) Bits 2:1
Default = 00
Function: To select the RMCK-to-LRCK ratio.
Note:
