Each bit can be configured as a wake-up input by OTP option. Software instructions determine the CMOS output or Schmitt trigger input with or without pull-high resistor (OTP option). PB0~PB7 I/O Pull-high or None Bidirectional 8-bit I/O port. Software instructions determine the CMOS output or Schmitt trigger input (pull-high resistor depending on OTP op- tion). PC0~PC5 PC6/XIN I/O Pull-high or None Bidirectional 7-bit I/O port. Software instructions determine the CMOS output or Schmitt trigger input (pull-high resistor depending on OTP op- tion). XIN is pin-shared with PC6 XOUT ¾ 32kHz RTC Connected an external 32kHz crystal to XIN and XOUT. VSS ¾¾ Negative power supply, ground VDD ¾¾ Positive power supply VDDA ¾¾ DAC power supply VSSA ¾¾ DAC negative power supply, ground RES I ¾ Schmitt trigger reset input, active low INT I Falling Edge Trigger or Falling/Rising Edge Trigger External interrupt Schmitt trigger input without pull-high resistor. Choice falling edge trigger or falling/rising edge trigger by OTP option. Falling edge triggered active on a high to low transition. Rising edge triggered active on a low to high transition. Input voltage is the same as operating voltage. OSC1 OSC2 ¾ RC or Crystal OSC1 and OSC2 are connected to an RC network or a crystal (by OTP option) for the internal system clock. In the case of RC operation, OSC2 is the output terminal for 1/4 system clock. The system clock may come from the crystal, the two pins cannot be floating. AUD O ¾ Audio output for driving a external transistor or for driving HT82V733 NC ¾¾ No connection TEST ¾¾ No connection (open) HT86R384 Rev. 0.10 4 May 18, 2007 Preliminary |
