The PCM514x has a register map split into multiple pages. Pages 0 and 1 control of the DAC and other on-chip peripherals. Pages 44 through 52 are used for Coefficient A memory, while Pages 62-70 are coefficient B memory. Pages 152-186 contain the miniDSP instruction memory. Page 253 is where the Clock Flex Mode register is located.

RQPD Powerdown Request
When this bit is set, the DAC will be forced into powerdown mode, in which the power consumption would be minimum as the charge pump is also powered down. However, it will take longer to restart from this mode. This mode has higher precedence than the standby mode, that is, setting this bit along with bit 4 for standby mode will result in the DAC going into powerdown mode.

This bit controls whether to ignore the LRCK/BCK missing detection. The LRCK/BCK need to be in low state (not only static) to be deemed missing. When ignored an LRCK/BCK missing will not cause the DAC go into powerdown mode.
Default value: 0
0: Regard LRCK/BCK missing detection
1: Ignore LRCK/BCK missing detection
DCAS Disable Clock Divider Autoset
This bit enables or disables the clock auto set mode. When dealing with uncommon audio clock configuration, the auto set mode must be disabled and all clock dividers must be set manually. Addtionally, some clock detectors might also need to be disabled. The clock autoset feature will not work with PLL enabled in VCOM mode. In this case this feature has to be disabled and the clock dividers must be set manually.
Default value: 0
0: Enable clock auto set
1: Disable clock auto set
IPLK Ignore PLL Lock Detection
This bit controls whether to ignore the PLL lock detection. When ignored, PLL unlocks will not cause a clock error. The PLL lock flag at Page 0 / Register 4, bit 4 is always correct regardless of this bit.
Default value: 0
0: PLL unlocks raise clock error
1: PLL unlocks are ignored

These bits indicate the currently detected SCK ratio. Note that even if the SCK ratio is not indicated as error, clock error might still be flagged due to incompatible combination with the sampling rate. Specifically the SCK ratio must be high enough to allow enough DSP cycles for minimal audio processing when PLL is disabled. The absolute SCK frequency must also be lower than 50 MHz.

12.1.3 Coefficient Data Formats

All mixer gain coefficients are 24-bit coefficients using a 4.20 number format. Numbers formatted as 4.20 numbers have 4 bits to the left of the binary point and 20 bits to the right of the binary point. If the most significant bit is logic 0, the number is a positive number. If the most significant bit is a logic 1, then the number is a negative number. In this case, every bit must be inverted, a 1 added to the result.

12.1.4 Power Down and Reset Behavior

Register values including those in the Coefficient Memory and Instruction Memory should remain when the device is put into power down mode. (PG0 Reg 0x02).

Register values in the device are reset to defaults when bit 0 or 4 of (Pg0, Reg 0x01) is set to 1. Please see the register description for more information.
