• Erase-program cycles
Flash memory contents can be erased and reprogrammed up to 100 times.
• On-board programming modes
These modes can be used to program, erase, and verify flash memory contents. There are two
modes: boot mode, and user programming mode.
• Automatic bit-rate alignment
In boot-mode data transfer, the H8/3048F aligns its bit rate automatically to the host bit rate
(9600 bps, 4800 bps and 2400 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.
• PROM mode
As an alternative to on-board programming, the flash memory can be programmed and erased
in PROM mode, using a general-purpose PROM programmer.
• Protect modes
Flash memory can be program-, erase-, and/or verify-protected in hardware and software
protect modes.
