Programming the Built-In PROM
The MCU’s built-in PROM is programmed in PROM mode. PROM mode is set by pulling

low, as shown in figure 72. In PROM mode, the MCU does not operate, but it can be programmed
in the same way as any other commercial 27256-type EPROM using a standard PROM programmer and a
100-to-28-pin socket adapter. Recommended PROM programmers and socket adapters are listed in table
29.
Since an HMCS400-series instruction is ten bits long, the HMCS400-series MCU has a built-in conversion
circuit to enable the use of a general-purpose PROM programmer. This circuit splits each instruction into
five lower bits and five upper bits that are read from or written to consecutive addresses. This means that if,
for example, 16 kwords of built-in PROM are to be programmed by a general-purpose PROM programmer,
a 32-kbyte address space ($0000–$7FFF) must be specified.
