PA0~PA7 constitute an 8-bit bidirectional input/output port with Schmitt trig-
ger input capability. Each bit on port can be configured as a wake-up input by
options. PA0~PA3 can be configured as a CMOS output or NMOS input/out-
put with or without pull-high resistor by options. PA4~PA7 are always
pull-high NMOS input/output. Of the eight bits, PA0~PA1 can be set as I/O
pins or buzzer outputs by options. PA3 can be set as an I/O pin or as a PFD
output also by options.
