Option
Bidirectional 8-bit input/output port. Each bit can be configured as a
wake-up input by ROM code option. The input or output mode is con-
trolled by PAC (PA control register).
Pull-high resistor options: PA0~PA7
Pull-low resistor options: PA0~PA3
CMOS/NMOS/PMOS options: PA0~PA7
Wake-up options: PA0~PA7
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output or Schmitt trigger input with pull-high resistor (determined
by pull-high options).
The PB can be used as analog input of the analog to digital converter
(determined by options).
Pull-low resistor for options: PB2, PB3
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output or Schmitt trigger input with pull-high resistor (determined
by pull-high options).
The PB can be used as analog input of the analog to digital converter
(determined by options).
Wake-up options: PB4, PB7
Negative power supply, ground
Bidirectional I/O lines. Software instructions determine the CMOS out-
put or Schmitt trigger input with pull-high resistor (determined by
pull-high options).
PC2 can be used as PWM1 output
PC3 can be used as PWM2 output
Schmitt trigger reset input. Active low.
Positive power supply
3.3V regulator output
USBD+ or PS2 CLK I/O line
USB or PS2 function is controlled by software control register
USBD- or PS2 DATA I/O line
USB or PS2 function is controlled by software control register
OSCI, OSCO are connected to a 6MHz or 12MHz crystal/resonator
(determined by software instructions) for the internal system clock.
