6.5.2 Pull High and Open Drain Control of I/O
Some of the above I/O ports can be controlled with pull-high resistor or open drain by programming
the special register.
All pull-high resistors of the following descriptions are 100K
under 3.0 voltage test condition. After
power-on reset the following special register will all reset to 0H.
