NJU3102 n TERMINAL DESCRIPTION No. SYMBOL 4 PA0 5 PA1 6 PA2 7 PA3 FUNCTION 4-bit Input / Output PORTA. Selects a terminal circuit for PORT grouped with 4 lines from follows by the mask option. · C-MOS Input Terminal with Pull-up Resistance(IA) · C-MOS Input Terminal(IC) · C-MOS Output Terminal(OB) Maker Testing Terminal with Pull-down Resistance 8 TEST INPUT The terminal is recommended to connect to GND. Internal Oscillator Terminals. 9 OSC1 INPUT Connects a device selected from the ceramic or the crystal 10 OSC2 (OUTPUT) resonator, or the resistor, to these terminals for the internal oscillator. In the external clock operation, OSC1 is the external clock input terminal and OSC2 is normally open terminal. VSS – Power Source (0V) 11 12 RESET INPUT RESET Terminal. When the low level input-signal, the system is initialized. 13 PB0 INPUT/OUTPUT 4-bit Input / Output PORTB. Selects a terminal circuit for PORT grouped with 4 lines from 14 PB1 INPUT/OUTPUT 15 PB2 INPUT/OUTPUT follows by the mask option. · C-MOS Input Terminal with Pull-up Resistance(IA) 16 PB3 INPUT/OUTPUT · C-MOS Input Terminal(IC) · C-MOS Output Terminal(OB) 17 PC0 INPUT/OUTPUT 2-bit Input / Output PORTC. Selects a terminal circuit for PORT grouped with 2 lines from 18 PC1 follows by the mask option. · C-MOS Input Terminal with Pull-up Resistance(IA) · C-MOS Input Terminal(IC) · C-MOS Output Terminal(OB) When the ports are selected as the input terminal, PC0 operates also as RESTART signal input terminal to return ...
