6. REGISTER DESCRIPTION
All registers are read/write except for the chip I.D. and Revision Register and Interrupt Status Register which are
read only. See the following bit definition tables for bit assignment information. The default state of each bit after a
power-up sequence or reset is listed in each bit description. Unless otherwise specified, all “Reserved” bits must
maintain their default value.

Chip I.D. and Revision Register (Address 01h) (Read Only)
Power Control 1 (Address 02h)
Chip I.D. (Read Only)
I.D. code for the CS42L52.
Chip Revision (Read Only)
CS42L52 revision level.
Power Down ADC Charge Pump
Configures the power state of the ADC charge pump.
Power Down PGAx
Configures the power state of PGA channel x.
Notes:
1. The CS42L52 employs a clever scheme for controlling the power to the PGA when PASSTHRU
2. This bit should be used in conjunction with ADCxSEL and PGAxSEL bits to determine the analog
