Description
User Branch Destination Address
When no user branch is required, set address 0
(H'00000000). The user branch destination should be the
RAM space or external bus space to which on-chip
program is not transferred. Be careful not to branch to the
area without execution codes, or runaway or destruction
of the on-chip program area or the stack area is caused.
In case of runaway, the value of flash memory is not
guaranteed.
During the processing in the user branch destination, do
not download or initialize the on-chip program or initiate
programming/erasing program. Programming/erasing at
the return from the user branch destination is not
guaranteed. In addition, do not modify the data prepared
to be programmed. Also during the processing in the user
branch destination, do not modify the
programming/erasing interface register or make transition
to RAM emulation mode. After the user branch
processing has completed, use the RTS instruction to
return to programming/erasing program.
