ADV_N

16-Bit NOR uses AD<15:0> signals as address and data bus. Unused A<7:0> address must be

terminated with external 10k ohm pull-down resistor.

If the microcontroller has no AD<0> pin for 16-bit wide devices, the unused AD<0> signal with must be

terminated with an external 10k ohm pull-down resistor.

7.1.4 8-Bit NOR asynchronous bus interface

ADV_N

8-Bit NOR uses AD<7:0> signals as address and data bus. The unused high data bus AD<15:8> and

A<7:0> address bus must be terminated with external 10k ohm pull-down resistors.

7.1.5 16-Bit General Multiplex asynchronous bus interface
