(b) Flash user branch address setting parameter (FUBRA: general register ER1 of CPU)
This parameter sets the user branch destination address. A specified user program can be used to
perform programming or erasing of processing units of predetermined size. When using the user
branch function, set the flash user branch enable bits in FPEFEQ to H'AA55 in addition to the
settings in this register.

Description
User branch destination address
The user branch destination should be located in a space
in RAM other than that to which internal programs are
transferred or the external bus space.
Be careful not to cause program runaway by branching to
an area without execution codes, and do not destroy an
area to which internal programs are downloaded or a
stack area. The contents of flash memory cannot be
guaranteed if program runaway occurs or if download or
stack areas are destroyed.
The user branch destination processing should not initiate
downloading of internal programs, initialization,
programming, or erasing. Programming or erasing cannot
be guaranteed when returning from the user branch
destination. Also, take care not to rewrite previously
prepared programming data.
Furthermore, do not rewrite program/erase interface
registers as part of the user branch destination
processing.
After user branch processing completes, use the RTS
instruction to return to the program/erase program.
