Section 19 ROM
19.20
19.20.1 PROM Mode Setting
Programs and data can be written and erased in PROM mode as well as in the on-board
programming modes. In PROM mode, the on-chip ROM can be freely programmed using a
PROM programmer that supports the Renesas microcomputer device type with 256-kbyte on-chip
flash memory (FZTAT256V3A). 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 19.34 shows PROM mode pin settings.
