The READ ID (90h) command is used to read identifier codes programmed into the
target. This command is accepted by the target only when all LUNs on the target are idle.
Writing 90h to the command register puts the target in read ID mode. The target stays in
this mode until another valid command is issued.
When the 90h command is followed by an 00h address cycle, the target returns a 5-byte
identifier code that includes the manufacturer's ID, device configuration, and part-
specific information.
When the 90h command is followed by a 20h address cycle, the target returns the 4-byte
ONFI identifier code.
After the 90h and address cycle are written to the target, the host enables data output
mode to read the identifier information. When the asynchronous interface is active, one
data byte is output per RE# toggle. When the synchronous interface is active, one data
byte is output per rising edge of DQS when ALE and CLE are HIGH; the data byte on the
falling edge of DQS is identical to the data byte output on the previous rising edge of
DQS.
