Section 17 Flash Memory
4. Compatibility with Programming/Erasing Program of Conventional F-ZTAT SH
Microcomputer
A programming/erasing program for flash memory used in the conventional F-ZTAT SH
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.
5. Monitoring Runaway by WDT
Unlike the conventional F-ZTAT SH microcomputer, no countermeasures are available for a
runaway by WDT during programming/erasing by the downloaded on-chip program.
Prepare countermeasures (e.g. use of the user branch routine and periodic timer interrupts) for
WDT while taking the programming/erasing time into consideration as required.
