P3D is a special function register (SFR) to set the value to be output to the Port 3 pin or to read the input level of
the Port 3. In output mode, the value of this register is output to the Port 3 pin. The value written to P3D is
readable. In input mode, the input level of the Port 3 pin is read when P3D is read.
Output mode or input mode is selected by using the port mode register (P3DIR) described later.
Description of Bits
