NMOS or
CMOS
Bidirectional 8-bit input/output port. Each pin can be configured as a
wake-up input by a configuration option. Software instructions determine if
the pin is a CMOS output or Schmitt Trigger input. Configuration options
determine if the pins have pull-high resistors. The INTB and TMR0 pins are
pin-shared with PA6 and PA7 respectively. PA0~PA3 are shared with the
SPIA function.PA4~PA5aresharedwithPWM0andPWM1.

with VDDIO
Bidirectional 8-bit input/output port. Each nibble, PB0~PB3 and PB4~PB7
pin can be configured as a wake-up input by a configuration option. Soft-
ware instructions determine if the pin is a CMOS output or Schmitt Trigger
input. Configuration options determine if the pins have pull-high resistors.
PB is pin shared with the A/D inputs. Once a PB line is selected as an A/D
input using software control, the I/O function and pull-high resistor are dis-
abled automatically. PB7 can be configured as a normal I/O or a VDDIO pin
by configuration option. The power supply for pins PB0~PB6 can be set to
either VDD or VDDIO by configuration options. PB0~PB3 are shared with
SPIB.
