21.10
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 *
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
