General Purpose I/O Module
12.3.1.2 Port Data Direction Registers (PDDR_x)
The PDDRs control the direction of the port x pin drivers when the pins are configured for general
purpose I/O. The PDDR_x registers are each eight bits wide, but not all ports use all eight bits. The
register definitions for all ports are shown in
The PDDRs are read/write. At reset, all bits in the PDDRs are cleared. Setting any bit in a PDDR_x
register configures the corresponding port x pin as an output. Clearing any bit in a PDDR_x
register configures the corresponding pin as an input.
