I designed GPIF as an Async SRAM interface.

No PACKET-related pins were assigned.

GPIF is a 16-bit data interface.

How should I write 8-bit data below?

if rqtCode = 0x01, Params[0] = 0x02, Params[1] = 0x03, Params[2] = 0x04, Params[3] = 0x05, Params[4] = 0x06, Params[5] = 0x07, Params[6] = 0x08,

Is it correct to write 16-bit Data in the first 0x0102, second 0x0304, Third 0x0506, fourth 0x0708 order?

Does the s-port automatically save to memory when 8 data are entered?

Enter 0x06 in rqtCode,

and aaa[0] to [7] should be insert data to store in eMMC memory?

The eMMC memory has no response from the Clock and Data pins.
