Register Map

Register Map Description

The register map is the primary way to configure the PCM186x-Q1 software-controlled devices. The register map is separated into four pages: 0,1,3, and 253. Page 0 handles all of the device configuration. Page 1 is used to indirectly program coefficients into the two fixed function DSPs on the PCM186x-Q1. Page 3 and page 253 contain additional registers for lower-power use. All undocumented registers are considered reserved; do not write to undocumented registers.

Change pages by writing to register 0x00 with the required page.

Reset registers by writing 0xFE to register 0x00.
