Five flash memory operating modes
The flash memory has five operating modes: program mode, program-verify mode, erase
mode, erase-verify mode, and prewrite-verify mode.
Block erase designation
Blocks to be erased in the flash memory address space can be selected by bit settings. The
address space includes a large-block area (eight blocks with sizes from 12 kbytes to 16 kbytes)
and a small-block area (eight 512-byte blocks).
Program and erase time
Programming one byte of flash memory typically takes 50 µs. Erasing all blocks (128 kbytes)
typically takes 1 s.
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.
