14. When downloading the programming/erasing program, do not clear the SCO bit in FCCS to 0
15. The contents of general registers ER0 and ER1 are not saved during download of an on-chip
H8S microcomputer which does not support download of the on-chip program by setting the
SCO bit in FCCS to 1 cannot run in this LSI. Be sure to download the on-chip program to
execute programming/erasure of the flash memory in this F-ZTAT H8SX microcomputer.
are not taken by WDT while programming/erasing and downloading a programming/erasing
program. When needed, measures should be taken by user. A periodic interrupt generated by
the WDT can be used as the measures, as an example. In this case, the interrupt generation
period should take into consideration time to program/erase the flash memory.
immediately after setting it to 1. Otherwise, download cannot be performed normally.
Immediately after executing the instruction to set the SCO bit to 1, dummy read of the FCCS
must be executed twice.

before a download request or before execution of initialization, programming, or erasure using
the procedure program.
