Description
Parameter ID (RFU)
Parameter Length (The number of following bytes in this parameter. Adding this value to the
current location value +1 = the first byte of the next parameter)

RFU
This parameter type (Parameter ID F0h) may appear multiple times and have a different length each time. The parameter is used to
reserve space in the ID-CFI map or to force space (pad) to align a following parameter to a required boundary.
10.3 Registers
The register maps are copied in this section as a quick reference. See Registers on page 48 for the full description of the register
contents.
