BSY> . While no automatic verify operation is performed internally to the device, be sure to read the
data to confirm that data has been correctly erased. Any new command sequence is not accepted while
it is in an automatic block erase operation. If it is desired to stop operation, use the hardware reset
function. In this case, it is necessary to perform the automatic block erase operation again because the
data erasing operation has not been normally terminated.

17-18 for table of protection bit addresses. This device assigns 1 bit to 1 block as a protection bit. The
applicable protection bit is specified by PBA in the seventh bus write cycle. By automatically program-
ming the protection bits, write and/or erase functions can be inhibited (for protection) individually for
each block. The protection status of each block can be checked by FCFLCS <BLPRO> to be described
later. This status of the automatic programming operation to set protection bits can be checked by
monitoring FCFLCS <RDY/BSY> . Any new command sequence is not accepted while automatic
programming is in progress to program the protection bits. If it is desired to stop the programming
operation, use the hardware reset function. In this case, it is necessary to perform the programming
operation again because the protection bits may not have been correctly programmed. If all the protection
bits have been programmed, all FCFLCS <BLPRO> are set to "1" indicating that it is in the protected
state. This disables subsequent writing and erasing of all blocks.
pending on the status of the protection bits and the security bits. It depends on the status of FCFLCS
<BLPRO> whether all <BLPRO> are set to "1" or not if FCSECBIT<FCSECBIT> is 0x1. Be sure to
check the value of FCFLCS <BLPRO> before executing the automatic protection bit erase command.
See the chapter "ROM protection" for details.
The automatic block erase operation starts when the sixth bus write cycle of the command cycle is

This device is implemented with protection bits. This protection can be set for each block. See Table
