2.1 I/O Cell List MB91V460
Note: This table shows the I/O cells used for MB91V460. Please refer to the appropriate datasheet for I/O circuits
used on flash devices.
Note: The most I/O cells have programmable input levels (CH / AH [/ TTL]). About the programming, see section
Port Input Level Selection on page 498
Note: For the programming of input pull-up or pull-down function, see section
Programmable Pull-Up/Pull Down
