Along with its on-board programming mode, this LSI also has programmer mode as a further
mode for programming and erasing of programs and data. In programmer mode, a general-purpose
PROM programmer can freely be used to program 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 256-kbyte flash memory as a device type*. Figure 20.18 shows
a memory map in programmer mode.
A status-polling system is adopted for operation in automatic program, automatic erase, and
status-read modes. In status-read mode, details of the system’s internal signals are output after
execution of automatic programming or automatic erasure. In programmer mode, provide a 12-
MHz input-clock signal.
Note: * In this LSI, set the programming voltage of the PROM programmer to 3.3 V.
