Is it necessary to add ALE with GPIF2 when FX3 is Slave?
Is it possible to always enable the operation?

Thanks,

Hello Tetsuo san,

Is it necessary to add ALE with GPIF2 when FX3 is Slave?

>> Adding ALE  will depend on your application. The Slave FIFO (AN65974) state machine doesn't use ALE when FX3 is configured as a slave.

ALE: Address Latch Enable is input to FX3. Enables the input address stage on the FX3 to latch address values. It is only available for asynchronous interface. ALE is used by the external processor (master) to notify the slave that the address bus is enabled generally when address bus and data bus are multiplexed.

 

Is it possible to always enable the operation?

>> Please let me know more about the application. 

Regards,
Rashi
