22.10 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-

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 22.10 shows programmer mode pin settings.
Notes: 1. Applies to the H8S/2148 and H8S/2144.
2. Applies to the H8/2147N and H8S/2142.
3. Use products other than the A-mask version of the H8S/2148, H8S/2147N, H8/2144,
and H8S/2142 (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.
