7.1 Examples of Bus Interface connection
7.1.1 16-Bit SRAM asynchronous bus interface
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.
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.
7.1.2 8-Bit SRAM asynchronous bus interface
8-Bit SRAM bus interface doesn’t use high AD<15:8> data bus, must terminate AD<15:8> signals 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.
