6.3.1 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 6-1. The MD1 to MD6 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 6-1 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 filter type selection Frame rate and BCLK frequency selection
MD2
MD3 I2S/LJ Mode: HPF Cut-off and Input Cap Quick Charge Selection CCLK Input
TDM Mode: Daisy Chain Enable/Disable
MD4 ADC Input Configuration (Differential/Single-ended, AC/DC Coupled)
MD5
MD6 I2S/LJ Mode: Mono/Stereo selection
TDM Mode: Daisy chain input
