Description
Bidirectional 8-bit input/output port. Each bit can be configured as a
wake-up input by configuration option. Software instructions determine if
the pin is a CMOS output or Schmitt trigger input with or without pull-high
resistor (determined by pull-high options: bit option). Pins PA0, PA1 and
PA3 are pin-shared with BZ, BZ and PFD, respectively.
Bidirectional 8-bit input/output port. Software instructions determine if
the pin is a CMOS output or Schmitt trigger input with or without pull-high
resistor (determined by pull-high option: bit option) or A/D input. Once a
PB line is selected as an A/D input (by using software control), the I/O
function and pull-high resistor are disabled automatically.
Bidirectional 8-bit input/output port. Software instructions determine if
the pin is a CMOS output or Schmitt trigger input with or without pull-high
resistor (determined by pull-high option: bit option).
Bidirectional 4-bit input/output port. Software instructions determine if
the pin is a CMOS output or Schmitt trigger input with or without pull-high
resistor (determined by pull-high option: bit option).
