19.13 Flash Memory Programmer Mode
19.13.1 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 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 19-18 shows programmer mode pin settings.

19.13.2 Socket Adapters and Memory Map
In programmer mode, a socket adapter is mounted on the PROM programmer to match the package concerned. Socket
adapters are available for each writer manufacturer supporting the Renesas Technology microcomputer device type with
128-kbyte on-chip flash memory.
Figure 19-24 shows the memory map in programmer mode. For pin names in programmer mode, see section 1.3.2, Pin
