Socket Adapters and Memory Map

In programmer mode, a socket adapter is mounted on the writer programmer to match the package

concerned. Socket adapters are available for each writer manufacturer supporting Renesas

Technology microcomputer device types with 128-kbyte or 64-kbyte on-chip flash memory.

Figure 22.15 shows the memory map in programmer mode. For pin names in programmer mode,

see section 1.3.2, Pin Functions in Each Operating Mode.

Programmer Mode Operation

Table 22.11 shows how the different operating modes are set when using programmer mode, and

table 22.12 lists the commands used in programmer mode. Details of each mode are given below.

• Memory Read Mode

Memory read mode supports byte reads.

• Auto-Program Mode

Auto-program mode supports programming of 128 bytes at a time. Status polling is used to

confirm the end of auto-programming.

• Auto-Erase Mode

Auto-erase mode supports automatic erasing of the entire flash memory. Status polling is used

to confirm the end of auto-erasing.

• Status Read Mode

Status polling is used for auto-programming and auto-erasing, and normal termination can be

confirmed by reading the FO6 signal. In status read mode, error information is output if an

error occurs.
