After clearing CCIF to launch the Read Resource command, four consecutive bytes are
read from the selected resource at the provided relative address and stored in the FCCOB
register. The CCIF flag sets after the Read Resource operation completes. The Read
Resource command exits with an access error if an invalid resource code is provided or if
the address for the applicable area is out-of-range.
23.4.11.5 Program Longword Command
The Program Longword command programs four previously-erased bytes in the program
flash memory or in the data flash memory using an embedded algorithm.
1. Must be 32-bit aligned (Flash address [1:0] = 00).

Table 23-45. Program Longword Command FCCOB Requirements
A Flash memory location must be in the erased state before
being programmed. Cumulative programming of bits (back-to-
back program operations without an intervening erase) within a
Flash memory location is not allowed. Re-programming of
existing 0s to 0 is not allowed as this overstresses the device.
