All of port options (except pull-up resistor of port 0) can be specified in bit unit.
*1
Memory select input for data security
*2
Output enable input
*3
Chip enable input
*4
Connect like the following figure to reduce noise into a VDD1 terminal.
Shorted the VSS1 terminal to the VSS2 terminal and to make the back-up time long.
*5
