boot mode and programmer mode.
the user MAT or user boot MAT can be programmed by
means of commands. Note that the contents of the MAT
cannot be read until this state.
Boot mode can be used for programming only the boot MAT
and then programming the user MAT in user boot mode.
Another way is to program only the user MAT since user boot
mode is not used.
• Two flash-memory MATs according to LSI initiation mode.
− The user memory MAT is initiated at a power-on reset in
− The user boot memory MAT is initiated at a power-on reset
• Three on-board programming modes
The on-chip flash memory has two memory spaces in the
same address space (hereafter referred to as memory
MATs). The mode setting at initiation determines which
memory MAT is initiated first.
The MAT can be switched by using the bank-switching
method after initiation.
Boot mode: Using the on-chip SCI-1, the user MAT can be
programmed/erased. In boot mode, the bit rate between the
host and this LSI can be adjusted automatically.
User program mode: Using a desired interface, the user
MAT can be programmed/erased.
User boot mode: The User boot program of The optional
interface can be made and The User MAT can be
programmed.
user mode: 160K bytes
in user boot mode: 8K bytes
program storage MAT. After the flash memory
related registers are checked, the reset vector is
fetched from the user boot MAT.
