General Purpose I/O Module
12.3.1.3 Port Pin Data/Set Data Registers (PPDSDR_x)
The PPDSDR_x registers reflect the current pin states and control the setting of output pins when
the pin is configured for general purpose I/O. The PPDSDR_x registers are each eight bits wide,
but not all ports use all eight bits. The register definitions for all ports are shown in
through
The PPDSDR_x registers are read/write. At reset, the bits in the PPDSDR_x registers are set to the
current pin states. Reading a PPDSDR_x register returns the current state of the port x pins. Setting
a PPDSDR_x register sets the corresponding bits in the PODR_x register. Writing 0s has no effect.
