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.  
If DMA transfers are not used the DACK and DREQ signals may be left floating or the DACK signal may be  
terminated with external 10k ohm pull-down resistor.

8-Bit General Multiplex 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.  
If DMA transfers are not used the DACK and DREQ signals may be left floating or the DACK signal may be  
terminated with external 10k ohm pull-down resistor.
