Part Number:66AK2H14
Hi,
I understood EMIF16 address mapping from below E2E thread and EMIF16 document(sprugz3a)
https://e2e.ti.com/support/processors/f/791/t/166642
For 16bit mode: EMIFA[22:0, 23]
For 8bit mode: EMIFA[21:0, 23, 22]
But customer reported that EMIFA behavior is the same for both 16bit and 8bit mode.
Customer uses ASIZE[1:0]=01b in AnCR registers.
If they access to 0x3800:0014, EMIFA[2:0, 23] = [1010].
If they access to 0x3800:0016, EMIFA[2:0, 23] = [1011].
So it seems A22 needs to be added to LSB. This is 8bit mode behavior as far as I understood.
What is the possible reason 16-bit mode works as 8-bit mode?
Thanks and regards,
Koichiro Tashiro
