The level of the pin can be read by reading the bit.
0 : “L” level
1 : “H” level
The pin level of any I/O port w hich is set to input mode
can be read by reading the corresponding bit in this
register. The pin level of any I/O port w hich is set to
output mode can be controlled by w riting to the
corresponding bit in this register.
