Section 17 ROM
17.13
17.13.1 Writer Mode Setting
Programs and data can be written and erased in writer mode as well as in the on-board
programming modes. In writer mode, the on-chip ROM can be freely programmed using a PROM
programmer that supports the Renesas Technology microcomputer device type with 128-kbyte on-
chip flash memory. Flash memory read mode, auto-program mode, auto-erase mode, and status
read mode are supported with this device type. 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 17.18 shows writer mode pin settings.
