DFLBCSTAT is a register which stores the results of a blank check command.
When on-chip ROM is disabled, the data read from DFLBCSTAT is 0000h and writing is disabled.
DFLBCSTAT is initialized by a reset, or when the FRESET bit in FRESETR is set to 1.
For FRESETR, see section 26.2.10, Flash Reset Register (FRESETR).
