Section 17 ROM
4. Monitoring runaway by WDT
17.28
Along with its on-board programming mode, this LSI also has a PROM mode as a further mode
for the writing and erasing of programs and data. In the PROM mode, a general-purpose PROM
programmer can freely be used to write programs to the on-chip ROM. Program/erase is possible
on the user MAT and user boot MAT. The PROM programmer must support Renesas Technology
microcomputers with 512-kbyte flash memory units as a device type.
A status-polling system is adopted for operation in automatic program, automatic erase, and
status-read modes. In the status-read mode, details of the system's internal signals are output after
execution of automatic programming or automatic erasure. In the PROM mode, provide a 12-MHz
input-clock signal.

Unlike the conventional F-ZTAT H8S 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.
