22.1 Features 675 Description added
• Two flash-memory MATs according to LSI initiation
mode.
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.
⎯ The user memory MAT is initiated at a power-on
reset in user mode: 160 Kbytes.
⎯ The user boot memory MAT is initiated at a
power-on reset in user boot mode: 8 Kbytes.
Description amended
• Three on-board programming modes
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 beprogrammed.

677 Notes amended
Notes: 1. All-erasure is performed. After that, the
specified block can be erased.
2. First, the reset vector is fetched from the
embedded program storage MAT. After the
flash memory related registers are checked,
the reset vector is fetched from the user
boot MAT.
