Section 18 ROM
18.1 Features
This LSI has an on-chip 512-kbyte flash memory. The flash memory has the following features.
• 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 in the 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: 512 kbytes
 The user boot memory MAT is initiated at a power-on reset in user boot mode:8 kbytes
• Three 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 and
user boot MAT can be programmed. This mode can automatically adjust the bit rate between host
and this LSI.
User program mode: The user MAT can be programmed by using the optional interface.
User boot mode: The user boot program of the optional interface can be made and the user MAT
can be programmed.
 Off-board programming mode
PROM mode: This mode uses the PROM programmer. The user MAT and user boot MAT can
be programmed.
• Programming/erasing interface by the download of on-chip program
This LSI has a dedicated programming/erasing program. After downloading this program to
the on-chip RAM, programming/erasing can be performed by setting the argument parameter.
 User branch*
The program processing is performed in 128-byte units. It consists the program pulse application,
verify read, and several other steps. Erasing is performed in one divided-block units and consists
of several steps. The user processing routine can be executed between the steps, this setting for
which is called the user branch addition.
Note: * Not available in the H8/3069R.
