9 / 59 page Pin Description of HT48C70 Pin Name I/O Mask Option Function PA0~PA7 I/O Wake-up Pull-high or None Bidirectional 8-bit input/output ports Each bit can be configured as a wake-up input by mask option. Software instructions determine the CMOS output or schmitt trigger input with or without pull high resistor (by mask option). PB0~PB7 I/O Pull-high or None Bidirectional 8-bit input/output ports Software instructions determine the CMOS output or schmitt trigger input (pull-high depends on mask option). VSS — — Negative power supply, GND INT I — External interrupt schmitt trigger with pull high resistor Edge trigger is activated during high to low transition. TMR0 I — Schmitt trigger input for timer/event counter 0 TMR1 I — Schmitt trigger input for timer/event counter 1 PC0~PC7 I/O Pull-high or None Bidirectional 8-bit input/output ports Software instructions determine the CMOS output or schmitt trigger input (pull-high depends on mask option). RES I — Schmitt trigger reset input, active low VDD — — Positive power supply OSC1 OSC2 I O Crystal or RC OSC1 and OSC2 are connected to an RC network or a crystal (by mask option) for the internal system clock. In the case of RC operation, OSC2 is the output terminal for 1/4 system clock. PD0~PD7 I/O Pull-high or None Bidirectional 8-bit input/output ports Software instructions determine the CMOS output or schmitt trigger input (pull-high depends on mask option). PE0~PE7 I/O Pull-high or None Bidirectional 8-bit input/output ports Software instructions determine the CMOS output or schmitt trigger input (pull-high depends on mask option). PF0~PF7 I/O Pull-high or None Bidirectional 8-bit input/output ports Software instructions determine the CMOS output or schmitt trigger input (pull-high depends on mask option). PG0~PG7 I/O Pull-high or None Bidirectional 8-bit input/output ports Software instructions determine the CMOS output or schmitt trigger input (pull-high depends on mask option).
