19.1
This series has 256, or 128 kbytes of flash memory, 256 or 128 kbytes of masked ROM, or 128 kbytes of PROM. The
ROM is connected to the H8S/2000 CPU by a 16-bit data bus. The CPU accesses both byte data and word data in one
state, making possible rapid instruction fetches and high-speed processing.
The on-chip ROM is enabled or disabled by setting the mode pins (MD
The flash memory versions of the H8S/2357 Group can be erased and programmed on-board as well as with a PROM
programmer.
The PROM version of the H8S/2357 Group can be programmed with a PROM programmer, by setting PROM mode.
19.1.1
Figure 19-1 shows a block diagram of the on-chip ROM.
19.1.2
The H8S/2357’s on-chip ROM is controlled by the mode pins and register BCRL. The register configuration is shown in
table 19-1.
