P4D is a special function register (SFR) to set the value to be output to the Port 4 pin or to read the input level of the
Port 4. In output mode, the value of this register is output to the Port 4 pin. The value written to P4D is readable.
In input mode, the input level of the Port 4 pin is read when P4D is read. Output mode or input mode is selected by
using the port mode register (P4DIR) described later.
[Description of Bits]
• P47D-P40D (bits 7-0)
Initial value
The P47D to P40D bits are used to set the output value of the Port 4 pin in output mode and to read the pin level of
the Port 4 pin in input mode.
