23.0.5.29 Port S Wired-OR Mode Register (WOMS)
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. It applies also to the SPI and SCI outputs and allows
a multipoint connection of several serial modules. These bits have no influence on pins used as
inputs.
