23.10
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
