Software instructions determined the CMOS out- put or Schmitt trigger with a pull-high resistor (determined by option). PB0~PB7 I/O Pull-high or None Bi-directional 8-bit I/O port. Software instructions determined the CMOS out- put or Schmitt trigger with a pull-high resistor (determined by option). AUD O ¾ Audio output for driving an external transistor or for driving HT82V733 PWM1 PWM2 O ¾ Audio PWM outputs 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. A configura- tion option determines if the interrupt active edge is a falling edge only or both a falling and rising edge. Falling edge triggered active on a high to low transi- tion. Rising edge triggered active on a low to high transition. Input voltage is the same as operating voltage. OSC1 OSC2 ¾ Crystal or RC OSC1, OSC2 are connected to an external RC network or external crystal, determined by configuration option, for the internal system clock. If the RC system clock option is selected, pin OSC2 can be used to measure the sys- tem clock at 1/4 frequency. VDD ¾¾ Positive digital power supply VSS ¾¾ Negative digital power supply, ground. VDDA ¾¾ Positive DAC circuit power supply VSSA ¾¾ Negative DAC circuit power supply, ground. HT86BXX/HT86BRXX Rev. 1.60 17 October 20, 2009 |
