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

Resistors on page 500
