Description
Serial Daisy Chain— Enables up to 16 devices to use a single CS
for serial port control. Connect SDITHRU pin from master device to
SDI pin of slave device. An internal pullup resistor holds this pin high
during idle periods.
Chip Select— Active low. When inactive, SCLK and SDIO are
ignored. When active, serial port is operational.
Differential Analog Transmit Output for SLIC Channel a.
Differential Analog Receive Input for SLIC Channel a.
Exposed Die Paddle Ground.
Connect to a low-impedance ground plane via topside PCB pad
directly under the part. See "12. Package Outline: 64-Pin eTQFP" on
page 123 for PCB pad dimensions.
