31-5 PRIM_ADD_TAG 0-7FF FFFFh Primary Address Tag Register
The primary address tag register selected by the DIAG_BUF_SEL bits in the
FDIAGCTRL register is memory-mapped here. This register can only be written in
privileged mode when diagnostic mode is enabled with DIAG_EN_KEY = 5h and
DIAGMODE = 5h in the FDIAGCTRL register. This register is not updated with new
Flash data if DIAG_EN_KEY is not equal to 5h or DIAGMODE is 0 or 7h. Valid reads
can occur in any mode. The register clears when an address tag error is found and
when leaving DIAG_MODE 5.
