Two on-board programming modes and one off-
board programming mode
⎯ On-board programming modes
Boot Mode: This mode is a program mode that uses
an on-chip SCI interface. The user MAT can be
programmed. This mode can automatically adjust
the bit rate between the host and this LSI.
User Program Mode: The user MAT can be
programmed by using an interface selected by the
user. This mode cannot be used on the 32 Kbyte
and 16 Kbyte flash memory versions.
