Mask Option
Description
PA0~PA7
I/O
Wake-up,
Pull-high
or None
Bidirectional 8-bit I/O port. 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
32kHz RTC
Connected an external 32kHz crystal to XIN and XOUT.
VSS
Negative power supply, ground
VDD
Positive power supply
VDDA
DAC power supply
VSSA
DAC negative power supply, ground
RES
I
Schmitt trigger reset input, active low
