PAD is a special function register (SFR) to set the value to be output to the Port A pin or to read the input level of the
Port A. In output mode, the value of this register is output to the Port 4 pin. The value written to PAD is readable.
In input mode, the input level of the Port A pin is read when PAD is read. Output mode or input mode is selected by
using the port mode register (PADIR) described later.
[Description of Bits]
• PA5D-PA0D (bits 5-0)
Initial value
The PA5D to PA0D bits are used to set the output value of the Port A pin in output mode and to read the pin level of
the Port A pin in input mode.
