18.9 PROM Mode
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
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.

18.9.1 Pin Arrangement of the Socket Adapter
Attach the socket adapter to the LSI in the way shown in figure 18.22. This allows conversion to
40 pins. Figure 18.21 shows the memory mapping of the on-chip ROM, and figure 18.22 shows
the arrangement of the socket adapter's pins.
