7.3.1 Hardware Control

The device supports simple hardware-pin-controlled options to select a specific mode of operation and audio interface for a given system as summarized in Table 7-1. The device is controlled through the MD0 to MD5 pins. MD1 to MD5 pins are connected to either logic low (VSS) or logic high (IOVDD), and the MD0 pin can be connected to AVDD or VSS through different pull-up or pull-down resistors.

Table 7-1 Pin Selectable Configurations Summary
PIN TARGET MODE CONTROLLER MODE
MD0 Multi-level analog input for controller/target mode and I2S/TDM/LJ mode selection
MD1 AVDD supply, word length, and decimation/interpolation filter type selection Frame rate and BCLK frequency selection
MD2
MD3 I2S/LJ Mode: Digital HPF cut-off frequency and input cap quick charge selection for the ADC Controller clock input
TDM Mode: Data slot selection
MD4 ADC input configuration (Differential/Single-ended, AC/DC Coupled) and DAC output configuration (Differential Line-out/ Differential Receiver or Headphone/ Single-ended Line-out/ Pseudo-differential Headphone)
MD5
