AM5728: GPMC Virtual and Default IO timing mode selection

Shareef
Expert 1985 points

Part Number: AM5728

Hi,

In my design, the GPMC interface is connected to 3 loads (memory devices) in asynchronous mode. As per Table 7-2 of datasheet, there are two modes

a. No Virtual or Manual Mode

b. GPMC_VIRTUAL1

In our case, we have used the GPMC_VIRTUAL1 timing mode in the pinmux. Following are my queries:

1. Should we actually select the No Virtual or Manual Mode?

2. What is the impact if we select GPMC_VIRTUAL1 mode for our use case? (Note: With GPMC_VIRTUAL1 mode, we have tested all the 3x memory interfaces to be working).

Thanks,

Shareef
