(2) Port direction register
When each terminal functions as a port, each correspondent pin are controlled by the port direction register to
following;
0 : Input mode
1 : Output mode
This bit becomes “0” after a reset.
Note : When accessing this register by using the instruction of the read modify write system (instructions such as
bit set) is mode, the bit targeted by an instruction becomes the defined value. However, the content of the
output register set to input with the other changes to input value of the pin at that time. Therefore, be sure
to write an expected value into PDR firstly, and then set DDR and finally change to the output when changing
the input pin to the output pin is made.
