TLV320AIC3111 Register Map
All features on this device are addressed using the I2C bus. All of the writable registers can be read back.
However, some registers contain status information or data, and are available for reading only.
The TLV320AIC3111 contains several pages of 8-bit registers, and each page can contain up to 128
registers. The register pages are divided up based on functional blocks for this device. The pages defined
for the TLV320AIC3111 are 0, 1, 3, 4–5 (ADC coefficient pages), 8–15 (DAC coefficient pages), 32–43
(ADC IRAM pages), and 64–95 (DAC IRAM pages). Page 0 is the default home page after RESET. Page
control is done by writing a new page value into register 0 of the current page.
The control registers for the TLV320AIC3111 are described in detail as follows. All registers are 8 bits in
width, with D7 referring to the most-significant bit of each register, and D0 referring to the least-significant
bit.
Pages 0, 1, 3, 4–5, 8–15, 32–43, and 64–95 are available for use; however, all other pages and registers
are reserved. Do not read from or write to reserved pages and registers. Also, do not write other than the
reset values for the reserved bits and read-only bits of non-reserved registers; otherwise, device
functionality failure can occur.
