24.9 Programmer Mode
Along with its on-board programming mode, this LSI also has programmer mode as another mode for writing and erasing
of programs and data. Programmer mode supports memory-read mode, auto-program mode, auto-erase mode, and status-
read mode. Programming/erasing is possible on the user MAT and user boot MAT.
A status-polling system is adopted for operation in auto-program mode, auto-erase mode, and status-read mode. In status-
read mode, details of the system's internal state are output after execution of automatic programming or automatic erasure.
In programmer mode, set the mode pins as shown in table 24.13, and provide a 6-MHz input-clock signal. This enables
this LSI to operate at 48 MHz.

24.9.1 Pin Arrangement of Socket Adapter
Attach the socket adapter to the LSI in the way shown in figure 24.25. This allows conversion to 40 pins. Figure 24.24
shows the memory mapping of on-chip ROM, and figure 24.25 shows the arrangement of the socket adapter's pins.
