Read Device Identifier
The Read Device Identifier command instructs the device to output manufacturer code,
device identifier code, block-lock status, OTP register data, or configuration register
data (see Section 6.2, “Device Command Bus Cycles” on page 18 for details on issuing
the Read Device Identifier command). Table 8, “Device Identifier Information” on
page 22 and Table 9, “Device ID codes” on page 22 show the address offsets and data
values for this device.
