1009 / 1348 page ![]() 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 CAN outputs and allows a multipoint connection of several serial modules. This bit has no influence on pins used as inputs. 24.0.5.33 Module Routing Register (MODRR) Read: Anytime. Write: Anytime. This register configures the re-routing of CAN0, CAN4, SPI0, SPI1 on alternative ports. Table 24-33.
