*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 TA ! PROM control signal input
*6 S0/T0 to S6/T6 : not provided the pull-down resistor
*7 S7/T7 to S15/T15 : provided the pull-down resistor (fixed)
*8 S16 to S31 : provided the pull-down resistor (fixed)
*9 S32 to S51 : not provided the pull-down resistor
