TLV320AIC3254-Q1: Using with a PIC micro

Part Number: TLV320AIC3254-Q1

I am using a PIC micro with the CODEC connected as SPI.  Purepath generated the file "base_main_rate44.cfg" for my project.  Looking at this file, it appears that all I have to do is send the page select commands and corresponding data via the SPI interface.  For instance the software reset would be $30 $00 $00 $01.  Is this the correct thinking?

  • Hi, Gary,

    Welcome to E2E and thank you for your interest in our products!

    That's correct. In order to configure the registers, you only need to select the page and then the corresponding data on each register of the selected page. The software reset in hex format would be as you mentioned:

    w 30 (i2c address) 00 (register address) 00 (register 0 data) 01 (register 1 data: software reset).
