INPUT/OUTPUT with selectable pull up resistor and 12 mA drive current. General
purpose memory mapped I/O port bit. Can be programmed to generate an internal
interrupt.
INPUT/OUTPUT with selectable pull up resistor and 12 mA drive current. General
purpose memory mapped I/O port. Can be programmed to generate an internal
interrupt.
INPUT/OUTPUT with open drain with 12 mA sink capability. Can be used to control
a LED connected to Vbat. Can be programmed to generate an internal interrupt.
Digital supply voltage
Digital ground
INPUT/OUTPUT with open drain with 100mA sink capability. This pin can be con-
figured as single ended buzzer driver with Pulse Width Modulated (PWM) output.
Can also be used for battery charge control.
INPUT/OUTPUT. General purpose memory mapped I/O port bit. P2[1,2] can be
configured as complementary PWM output for e.g. buzzer control. P2[1,2] can
drive 12 mA.

INPUT/OUTPUT. General purpose memory mapped I/O port bit.
INPUT/OUTPUT. General purpose memory mapped I/O port bit.
INPUT. Battery voltage. (upto 5V input)
Reserved for future onboard OTP ROM.
INPUT. Battery voltage. (upto 5V input)
INPUT. Testpin for production test must be connected to Vss.
INPUT. Power ON. Uses Vbat input supply.
INPUT. Charger connected indication. Uses Vbat input supply.
OUTPUT. Uses Vbat input supply. Switch external regulator on
DIGITAL OUTPUT/ANALOG INPUT. P2[5] 8 bit multiplexed ADC inputs. P2[5] can
also be used as a digital output
OUTPUT. Positive microphone reference
INPUT. Positive microphone input
POWER. Signal ground.
INPUT. Negative microphone input.
OUTPUT. Negative microphone reference
OUTPUT. Negative loudspeaker output
OUTPUT. Positive loudspeaker output
Analog supply voltage for CODEC, Xtal oscillator and 8 bit DAC (pin 63)
Analog ground.
8 bit DAC output for frequency control.
External capacitor.
INPUT. 10.368MHz crystal connection.
Digital ground
Digital supply voltage
INPUT/OUTPUT. Active low Reset input with open collector output and pull down
resistor.
INPUT with pull down. Hold processor operation. For e.g. In Circuit Emulation. The
system bus interface will TRI-STATE data and address bus and all control signals.
In this mode an external CR16A can control the SC14402 completely.
