Bidirectional 8-bit input/output port. Each pin can be configured as a
wake-up input by a configuration option. Software instructions deter-
mine if the pin is a CMOS output or NMOS, PMOS or Schmitt Trigger
input. Configuration options determine if the structures are CMOS,
NMOS or PMOS types. Configuration options determine if the pins
have pull-high resistors. TMR0 and TMR1 are pin-shared with PA6 and
PA7, respectively.
Bidirectional 8-bit input/output port. Each nibble can be configured 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 if the pins have pull-high resistors. The power supply
of PB0~PB7 can be optioned as VDD or V33O output.
