0x15: Data Stored in Non-erasable Flash Report
A section of non-erasable ROM is reserved for customer data blocks. There is no
HIPPO command to set the data; data can only be set in Monitor mode. The data
blocks are written serially into an area of ROM that cannot be erased or
overwritten.
Each subcode corresponds to a different data block type. Unlike standard
HIPPO, the parser is defined by the customer, so the message length and data
content are not specified by the parser code and subcode. The maximum data
block length is 128 bytes.
When queried with a subcode, the report scans the section of ROM and returns
the last data block entry with that subcode. The customer can effectively “update”
a data block by writing a new data block with the same subcode and updated
data, provided that there is room left in the allocated ROM section (approximately
2K bytes).
If no data block is found with the queried subcode, the module returns an
acknowledgment with “Data not available”.
The “query all subcodes” mode 0xFF is not available.
