Description
M- Inverting Microphone (Input). Inverting input to microphone amplifier from the handset
microphone.
M+ Non-Inverting Microphone (Input). Non-inverting input to microphone amplifier from the
handset microphone.
VBias
VRef
PWRST
Bias Voltage (Output). (VDD/2) volts is available at this pin for biasing external amplifiers.
Connect 0.1 µF capacitor to VSSA.
Reference voltage for codec (Output). Nominally [(VDD/2)-1.5] volts. Used internally.
Connect 0.1 µF capacitor to VSSA.
Power-up Reset (Input). CMOS compatible input with Schmitt Trigger (active low).
IC
VSSD
CS
Internal Connection. Tie externally to VSS for normal operation.
Digital Ground. Nominally 0 volts.
Chip Select (Input). This input signal is used to select the device for microport data
transfers. Active low. TTL level compatible.
SCLK Serial Port Synchronous Clock (Input). Data clock for microport. TTL level compatible.
DATA1 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 DATA2 pin. TTL level compatible input levels.
DATA2 Serial Data Receive. In Motorola/National mode of operation, this pin is used for data
receive to the IDPC. In Intel mode, serial data transmit and receive are performed on the
DATA1 pin and DATA2 is disconnected. Input level TTL compatible.
WD Watchdog (Output). Watchdog timer output. Active high.
IRQ Interrupt Request (Open Drain Output). Low true interrupt output to microcontroller.
