code area in programmer mode, a verification error will occur unless a countermeasure is taken
for the PROM programmer and its program version.
12. The programming program that includes the initialization routine and the erasing program that
includes the initialization routine are each 2 kbytes or less. Accordingly, when the CPU clock
frequency is 20 MHz, the download for each program takes approximately TBD µs at the
maximum.
13. A programming/erasing program for flash memory used in the conventional H8S F-ZTAT
microcomputer which does not support download of the on-chip program by a SCO transfer
request cannot run in this LSI. Be sure to download the on-chip program to execute
programming/erasing of flash memory in this LSI.
14. Unlike the conventional H8S F-ZTAT microcomputer, no countermeasures are available for a
runaway by the WDT during programming/erasing. Prepare countermeasures (e.g. use of the
periodic timer interrupts) for the WDT with taking the programming/erasing time into
consideration as required.
