Read Electronic Signature
The device contains a Manufacturer Code and Device Code. To read these codes two steps
are required:
1. first use one Bus Write cycle to issue the Read Electronic Signature command (90h),
followed by an address input of 00h.
2. then perform two Bus Read operations – the first will read the Manufacturer Code and
the second, the Device Code. Further Bus Read operations will be ignored.
Refer to Table 12: Electronic signature, for information on the addresses.
