CS8420
13.5.1 Pin Description - Hardware Mode 4
Overall Device Control:
DFC0, DFC1 - Data Flow Control Inputs
DFC0 and DFC1 inputs determine the major data flow options available in Hardware mode, according to
Table
5.
Audio Input Interface:
SDIN - Serial Audio Input Port Data Input
Audio data serial input pin. This data will be transmitted out the AES3 port.
ISCLK - Serial Audio Input Port Bit Clock Input or Output
Serial bit clock for audio data on the SDIN pin.
ILRCK - Serial Audio Input Port Left/Right Clock Input or Output
Word rate clock for the audio data on the SDIN pin. The frequency will be at the input sample rate (Fsi)
APMS - Serial Audio Input Port Master or Slave
APMS should be connected to VD+ to set serial audio input port as a master, or connected to DGND to set the port
as a slave.
Audio Output Interface:
SDOUT - Serial Audio Output Port Data Output
Audio data serial output pin. This is also a start-up option pin, and requires a pull-up or pull-down resistor.
