• Automatic bit rate adjustment
⎯ With data transfer in SCI boot mode, this LSI's bit rate can be automatically adjusted to
match the transfer bit rate of the host.
• Programming/erasing protection
⎯ Sets hardware protection, software protection, and error protection against flash memory
programming/erasing.
• Programmer mode
⎯ Flash memory can be programmed/erased in programmer mode, using a PROM

onto flash memory.
