28.3.2 Program Flash IFR Map
The program flash IFR is nonvolatile information memory that can be read freely, but the
user has no erase and limited program capabilities (see the Read Once, Program Once,
and Read Resource commands in Read Once Command, Program Once Command and
Read Resource Command). The contents of the program flash IFR are summarized in the
following table and further described in the subsequent paragraphs.
For devices that only contain program flash, the program flash IFR is located within the
program flash 0 memory block.
