Flash Memory Programmer Mode

21.10.1

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*

*3 or 64-kbyte*2 *3 on-chip flash memory. 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 21.10 shows programmer mode pin settings.

Notes: 1. Applies to the H8S/2138 and H8S/2134

2. Applies to the H8S/2132.

3. Use products other than the A-mask version of the H8S/2138, H8S/2134, and

H8S/2132 (in either 5-V or 3-V version) with the writing voltage for the PROM

programmer set to 5.0 V. Do not use the A-mask version with a 5.0-V PROM

programmer setting.
