14.8
Along with its on-board programming mode, this LSI also has a programmer mode as a further
mode for the writing and erasing of programs and data. In the programmer 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’s microcomputers with 258-kbyte flash memory as a device type*.
Figure 14.20 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 the 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.
