Figure 20.1 shows a block diagram of the flash memory.
Automatic bit-rate alignment
In boot-mode data transfer, the H8/3437F aligns its bit rate automatically to the host bit rate
(maximum 9600 bps).
Flash memory emulation by RAM
Part of the RAM area can be overlapped onto flash memory, to emulate flash memory updates
in real time.
Writer mode
As an alternative to on-board programming, the flash memory can be programmed and erased
in writer mode, using a general-purpose PROM programmer. Program, erase, verify, and other
specifications are the same as for HN28F101 standard flash memory.
