Description
Chip Select.
Active low. When inactive, SCLK and SDI are ignored and SDO
is high impedance. When active, serial port is operational.
Senses ring-trip condition when using centralized ring generator.
Connect to high side of ring sense resistor. Shared by channel a
and b.
Exposed Die Paddle Ground.
Connect to a low-impedance ground plane via top side PCB pad
directly under the part. See Package Outlines: 64-Pin TQFP for
PCB pad dimensions.
Ring Generator Sensing Input.
