4.5.1 DataBlaze Notes
The “Mass Erase” operation always blanks the device (even if the
device is protected or secured) and “unsecures” the device (the FLASH
Options/Security Byte location is programmed with 0xFE).
The “Blank Check” operation doesn’t blank check the FLASH
Options/Security Byte location.
The “Program” operation automatically verifies the programmed data by
reading back the programmed data and checking it against the buffer
sent to the target device. The “Verify” operation is much more secure
(but slower), since it reads back the programmed data and checks it
against the data buffer present in the host PC.
In case of verifying error, please verify the value programmed to the
FLASH Options/Security Byte location. The bit 0 of this byte is always
programmed to 0, so any attempt to program it to 1 will cause a
verifying error.
