High Voltage Ports as General Digital I/O
Configuring the Pin
Reading the Pin
The high voltage ports are high voltage tolerant open collector output ports. In addition they can
be used as general digital inputs.

Each port pin consist of two register bits: PORTxn and PINxn. As shown in

the PINx I/O address.
If PORTxn is written logic one, the port pin is driven low (zero). If PORTxn is written logic zero,
the port pin is tri-stated. The port pins are tri-stated when a reset condition becomes active, even
if no clocks are running.
The port pin can be read through the PINxn Register bit. As shown in
Register bit and the preceding latch constitute a synchronizer. This is needed to avoid metasta-
bility if the physical pin changes value near the edge of the internal clock, but it also introduces a
delay.
