7.6.7 Register 6 - Pull-up/pull-down select port 0 register
When bus-hold feature is not selected and bit 1 of Register 4 is set to logic 1, the I/O
port 0 can be congured to have pull-up or pull-down by programming the
pull-up/pull-down register. Setting a bit to logic 1 will select a 100 k
pull-up resistor for
that I/O pin. Setting a bit to logic 0 will select a 100 k
pull-down resistor for that I/O pin. If
the bus-hold feature is enabled, writing to this register will have no effect on
pull-up/pull-down selection.
7.6.8 Register 7 - Pull-up/pull-down select port 1 register
When bus-hold feature is not selected and bit 1 of Register 5 is set to logic 1, the I/O
port 1 can be congured to have pull-up or pull-down by programming the
pull-up/pull-down register. Setting a bit to logic 1 will select a 100 k
pull-up resistor for
that I/O pin. Setting a bit to logic 0 will select a 100 k
pull-down resistor for that I/O pin. If
the bus-hold feature is enabled, writing to this register will have no effect on
pull-up/pull-down selection.
