PA3 or PFD
I/O or Serial
Bus
Bidirectional 8-bit input/output port. Each bit can be configured as wake-up
input by option (bit option). Software instructions determine the CMOS out-
put or Schmitt trigger input with or without pull-high resistor (determined by
pull-high options: bit option). The PFD and INT are pin-shared with PA3
and PA5, respectively. Once the I
2
C Bus function is used, the internal reg-
isters related to PA6 and PA7 cannot be used.

I/O
Pull-high
Bidirectional 8-bits input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without pull-high resistor (deter-
mined by pull-high option: bit option) or A/D input. Once a PB line is se-
lected as an A/D input (by using software control), the I/O function and
pull-high resistor are automatically disabled.
