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 (mask 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 mask 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 mask 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 HT86XXX Rev. 1.70 11 May 6, 2004 |
