Chapter 3 Port Integration Module (PIM9NE64V1)
3.3.2.6.7
Read:Anytime.
Write:Anytime.
This register configures the output pins as wired-or. If enabled the output is driven active low only
(open-drain). A logic level of “1” is not driven. This bit has no effect on pins used as inputs.
WOML[6:0] — Wired-Or Mode Port L
3.4
Each pin can act as general-purpose I/O. In addition the pin can act as an output from a peripheral module
or an input to a peripheral module.
A set of configuration registers is common to all ports. All registers can be written at any time, however a
specific configuration might not become active.
Example:
Selecting a pull-up resistor. This resistor does not become active while the port is used as a push-pull
output.
3.4.1
This register holds the value driven out to the pin if the port is used as a general-purpose I/O.
Writing to this register has only an effect on the pin if the port is used as general-purpose output. When
reading this address, the value of the pins are returned if the data direction register bits are set to 0.
If the data direction register bits are set to 1, the contents of the I/O register is returned. This is independent
of any other configuration
3.4.2
This is a read-only register and always returns the value of the pin
Data direction register

1 = Open-drain mode enabled for output buffers.
0 = Open-drain mode disabled for output buffers.
