Flash Memory Programmer Mode

23.10.1

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 or 64-kbyte on-chip flash memory*. See section 23.10.10, Notes on Memory Programming

and section 23.11, Flash Memory Programming and Erasing Precautions, for notes on programmer

mode. 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 23.10 shows programmer mode pin settings.

Note: *

Use products of the H8S/2148 A-mask version, H8S/2147 A-mask version, and

H8S/2144 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 3.3V PROM programmer setting.
