Bit 7-2: Not Used
Bit 1:
PRTCD
Page Protected
0: The writing has been completed
1: The writing has been aborted because the
page is protected.
Bit 0:
ABRT
Writing operation aborted
0: The writing has been completed
1: The writing has been aborted because an
interrupt or another unspecified cause
occurred.
The ABRT and PRTCD bits are reset after thenext
successful data writing in the Flash of EEPROM
memory.
