The pin level on any I/O port which is
set for input mode can be read by
reading the corresponding bit in this
register.
The pin level on any I/O port which is
set for output mode can be controlled
by writing to the corresponding bit in
this register
0 : “L” level
1 : “H” level (Note 1)
(i = 0 to 7 and 9)
