I/O
Pull-high*
Wake-up
PA3 or PFD
Bidirectional 8-bit input/output port. Each individual pin on this port can be config-
ured as a wake-up input by a configuration option. Software instructions deter-
mine if the pin is a CMOS output or Schmitt trigger input. Configuration options
determine which pin on this port have pull-high resistors. The PFD, TMR and ex-
ternalinterruptinputarepin-sharedwithPA3,PA4,andPA5,PA6,respectively.
PB0/AN0~
PB7/AN7
I/O
Pull-high*
Bidirectional 8-bit input/output port. Software instructions determine if the pin is a
CMOS output or Schmitt trigger input. Configuration options determine which pin
on this port have pull-high resistors. PB is pin-shared with the A/D input pins. The
A/D inputs are selected via software instructions Once selected as an A/D input,
the I/O function and pull-high resistor functions are disable automatically.
PB2, PB3 has CMOS or NMOS output option.
PC0/AN8~
PC7/AN15
I/O
Pull-high*
Bidirectional 8-bit input/output port. Software instructions determine if the pin is a
CMOS output or Schmitt trigger input. Configuration options determine which pin
on this port have pull-high resistors. PB is pin-shared with the A/D input pins. The
A/D inputs are selected via software instructions Once selected as an A/D input,
the I/O function and pull-high resistor functions are disabled automatically.
PD0/PWM0
PD1/SCS_A
PD2/SCK_A
PD3/SDI_A
PD4/SDO_A
PD5~PD6
PD7/SDO_B
I/O
Pull-high*
PD0 or PWM
Bi-directional 8-bit input/output port. Software instructions determine if the pin is a
CMOS output or Schmitt trigger input. Configuration options determine which pin
on this port have pull-high resistors. PD0 is pin-shared with the PWM output se-
lected via configuration option.
PD1~PD4 are pin-shared with SPI interface A.
PD4, PD7 have CMOS or NMOS output options.
PD7 is pin-shared with the SPI interface B.
PF0/SDI_B
PF1/SCK_B
PF2/SCS_B
I/O
Pull-high*
Bidirectional 3-bit input/output port. Software instructions determine if the pin is a
CMOS output or Schmitt trigger input. Configuration options determine which pin
on this port have pull-high resistors. PF0~PF2 is pin-shared with the SPI interface
B.
OSC1
OSC2
I
O
Crystal
or RC
OSC1 and OSC2 are connected to an external RC network or external crystal, de-
termined by configuration option, for the internal system clock. If the RC system
clock is selected, pin OSC2 can be used to measure the system clock at 1/4 sys-
tem frequency.
RES
I
Schmitt trigger reset input. Active low
VDD
Positive power supply
VSS
Negative power supply, ground
AVDD
Analog positive power supply
AVSS
Analog negative power supply
VREF
8-bit A/D reference voltage input pin
Note: * The pull-high resistors of each I/O port are controlled by options.
