7 Register Descriptions
All registers are read/write except for the chip ID, revision register, and status registers, which are read only. Refer to the
following bit definition tables for bit assignment information. The default state of each bit after a power-up sequence or
reset is indicated. All reserved registers must maintain their default state.

PDN_ULP
CS53L30 power down. Configures the power state of the entire device. After power-up (PDN_ULP: 1
 0), subblocks
stop ignoring their individual power controls and are powered according to their settings. PDN_ULP has precedence over
PDN_LP (i.e., if PDN_ULP is set, the ADC and references are all powered down).
0 (Default) Powered up, as per the individual x_PDN controls.
1 Powered down. After PDN_ULP is set and the entire device is powered down, PDN_DONE is set, indicating that
MCLK can be removed.
6
PDN_LP
Partial CS53L30 power down. Configures the power state of the device, with the exception of the reference circuits to
allow for faster startup during power cycles. After power up (PDN_LP: 1
0), subblocks stop ignoring their individual
power controls and are powered according to their settings.
0 (Default) Powered up, as per the individual x_PDN controls.
1 Powered down.
Note: If PDN_ULP is set, the value of PDN_LP is ignored.
