21.1.1
The H8/3437SF has 60 kbytes of on-chip flash memory. The ROM is connected to the CPU by a
16-bit data bus. The CPU accesses both byte data and word data in two states. Even addresses are
connected to the upper 8 bits, and odd addresses to the lower 8 bits. Word data must start at an
even address.
Enabling and disabling of the on-chip ROM is performed by the mode pins (MD
the EXPE bit in MDCR.
The H8/3437SF flash memory can be programmed and erased on-board as well as with a PROM
programmer.
