Pull-up resistors
P00 to P07,
P10 to P17,
P20 to P27,
P40 to P47,
P50 to P53,
P60 to P65
Selectable per pin.
Pull-ups for pins P40 to
P47 and P60 to P65
can only be specified,
however, when the
LCD segment output
option is not selected.
Also, P50 to P53 must
be set to without a pull-
up resistor when an A/
D converter is used.
Selectable per pin by
pull-up control
registers. Pull-up
resistors are not
available for P20 to
P27, P40 to P47 and
P60 to P65.
Furthermore, P50 to
P53 must be set to
without a pull-up
resistor when an A/D
converter is used.
Selectable per pin by
pull-up control
registers. Pull-up
resistors are not
available for P20 to
P27, P40 to P47 and
P60 to P65.
Furthermore, P50 to
P53 must be set to
without a pull-up
resistor when an A/D
converter is used.
