Description
Command Buffer Empty Flag — The FCBEF bit is used to launch commands. It also indicates that the
command buffer is empty so that a new command sequence can be executed when performing burst
programming. The FCBEF bit is cleared by writing a 1 to it or when a burst program command is transferred to
the array for programming. Only burst program commands can be buffered.
0 Command buffer is full (not ready for additional commands).
1 A new burst program command can be written to the command buffer.
Command Complete Flag — FCCF is set automatically when the command buffer is empty and no command
is being processed. FCCF is cleared automatically when a new command is started (by writing 1 to FCBEF to
register a command). Writing to FCCF has no meaning or effect.
0 Command in progress
1 All commands complete
Protection Violation Flag — FPVIOL is set automatically when a command that attempts to erase or program
a location in a protected block is launched (the erroneous command is ignored). FPVIOL is cleared by writing a
1 to FPVIOL.
0 No protection violation.
1 An attempt was made to erase or program a protected location.
