Flash Memory Programmer Mode

22.10.1

Programmer Mode Setting

Programs and data can be written and erased in programmer mode as well as in the on-board

programming modes. In programmer mode, the on-chip ROM can be freely programmed using a

PROM programmer that supports Renesas Technology microcomputer device types with 128-

kbyte on-chip flash memory*. For precautions concerning the use of programmer mode, see

section 22.10.10, Notes on Memory Programming and section 22.11, Flash Memory Programming

and Erasing Precautions. Flash memory read mode, auto-program mode, auto-erase mode, and

status read mode are supported with these device types. In auto-program mode, auto-erase mode,

and status read mode, a status polling procedure is used, and in status read mode, detailed internal

signals are output after execution of an auto-program or auto-erase operation.

Table 22.10 shows programmer mode pin settings.

Note: *

Use products of the H8S/2138 A-mask version (in either 5-V or 3-V version) with the

writing voltage for PROM programmer set to 3.3 V. Do not use products other than the

A-mask version with 3.3-V PROM programmer setting.
