Internal Connection. Tie externally to V
A/ - When internal control bit DEn = 0 this CMOS level compatible input pin governs
the companding law used by the filter/Codec; -Law when tied to V
when tied to V
IRQ - When internal control bit DEn = 1 this pin becomes an open-drain interrupt
output signalling valid access to the D-Channel registers in ST-BUS mode.
Digital Ground. Nominally 0 volts.
Chip Select (Input). This input signal is used to select the device for microport data
transfers. Active low. CMOS level compatible.
Serial Port Synchronous Clock (Input). Data clock for microport. CMOS level
compatible.
Bidirectional Serial Data. Port for microprocessor serial data transfer. In Motorola/
National mode of operation, this pin becomes the data transmit pin only and data
receive is performed on the DATA 2 pin. Input CMOS level compatible.
Serial Data Receive. In Motorola/National mode of operation, this pin is used for
data receive. In Intel mode, serial data transmit and receive are performed on the
DATA 1 pin and DATA 2 is disconnected. Input CMOS level compatible.
