7 / 34 page KS86C4302/C4304/P4304 PRODUCT OVERVIEW 1-7 PIN DESCRIPTIONS Table 1-1. KS86C4302/C4304 Pin Descriptions Pin Names Pin Type Pin Description Circuit Type Share Pins P0.0-P0.3 I/O Bit-programmable I/O port for Schmitt trigger input or push-pull, open-drain output. Pull-up resistors are assignable by software. Port 0 pins can also be used as alternative function. E BUZ PWM INT0/T0CK INT1 P1.0-P1.4 I/O Bit-programmable I/O port for Schmitt trigger input or push-pull, open-drain output. Pull-up resistors are assignable by software. Port 1 pins can also be used as alternative function. E-1 ADC0-ADC4 SI SO SCK CLO P2.0-P2.3 O Push-pull or open-drain output port. Pull up resistors are assignable by software. Port 2.0-2.1 pins can also be used as alternative function. E-2 SCK SO XIN, XOUT – Crystal/ceramic, or RC oscillator signal for system clock. – – RESET I System RESET signal input pin. B – TEST I Test signal input pin (for factory use only: must be connected to VSS) – – VDD, VSS – Voltage input pin and ground – – AVREF – A/D converter reference voltage input and ground – – AVSS Bonded to VSS internally SCK I/O Serial interface clock I/O E-1 E-2 P1.3 or P2.0 SO O Serial data output E-1 E-2 P1.2 or P2.1 SI I Serial data input E-1 P1.1 CLO O System clock output port E-1 P1.4 BUZ O 200 Hz- 20 kHz frequency output for buzzer sound E P0.0 PWM O 12-bit PWM output E P0.1 INT0-INT1 I External interrupt input port E P0.2 P0.3 T0CK I Timer 0 external clock input E P0.2 ADC0-ADC4 I A/D converter input E-1 P1.0-P1.4 |
