Programmer Mode
Along with the 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 be used to freely write programs to the on-chip ROM.
Program/erase is possible on the user MAT. The PROM programmer must support Renesas
microcomputers with 256-Kbyte flash memory 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.
