NOTES:
1. No redirection if FPOPEN = 0, or FNORED = 1.
2. Reset vector is not redirected.
3. Use for 60K version only. When protecting all of 32K version memory, use FPOPEN = 0.
4.6.5 FLASH Status Register (FSTAT)
Bits 3, 1, and 0 always read 0 and writes have no meaning or effect. The remaining five bits are status bits
that can be read at any time. Writes to these bits have special meanings that are discussed in the bit
descriptions.

FCBEF — FLASH 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.
1 = A new burst program command may be written to the command buffer.
0 = Command buffer is full (not ready for additional commands).
