This LSI has 512-kbyte (H8S/2556, H8S/2552, and H8S/2506) or 384-kbyte (H8S/2551 and
H8S/2505) of on-chip flash memory. Features of flash memory are shown below.
20.1
• Two flash-memory MATs according to LSI initiation mode
• Three on-board programming modes and one off-board programming mode
• One off-board programming mode
• Programming/erasing interface by the download of on-chip program
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:
⎯ The user boot memory MAT is initiated at a power-on reset in user boot mode: 8 kbytes
⎯ Boot mode
⎯ User program mode
⎯ User boot mode
⎯ Programmer mode
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.
The user branch is also supported.
512 kbytes (H8S/2556, H8S/2552, and H8S/2506)
384 kbytes (H8S/2551 and H8S/2505)
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.
The user MAT can be programmed by using the optional interface.
The user boot program of the optional interface can be made and the user MAT can be
programmed.
This mode uses the PROM programmer. The user MAT and user boot MAT can be
programmed.
