Flash Memory Programmer Mode
17.20.1 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 the Renesas Technology microcomputer device type with 512-
kbyte on-chip flash memory (FZTAT512V3A). 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 17-34 shows programmer mode pin settings.
