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.
All “Reserved” registers must maintain their default state.

Chip I.D. and Revision Register (Address 01h) (Read Only)
Chip I.D. (Chip_ID[4:0])
Default: 11011
Function:
I.D. code for the CS53L21. Permanently set to 11011.
Chip Revision (Rev_ID[2:0])
Default: 001
Function:
CS53L21 revision level. Revision B is coded as 001. Revision A is coded as 000.
