Question:How to set ROM Block Configuration

For ROM Block Configuration setting, areas where the same block size continues are registered as one group.
The flash block represents the minimum erase unit of flash memory.

ROM Block Configuration registration rules

1.Information on the head address of the flash memory (address on the buffer memory) is registered in Group 1
2.Information on an address (address on the buffer memory) which is a change in block size is registered in Group 2 and subsequent
3.Register the address which the memory type (code flash, data flash, EEPROM, etc.) and the address of the area where the real address area changes (address on the buffer memory)

※Depending on your using Micom Pack, some memory areas are treated as consecutive addresses on the buffer memory. In that case, it is necessary to register with the virtual buffer memory address. For the address map on the buffer memory, please refer to the manual of each Micom Pack.

Setting example of ROM Block Configuration

When it consists of the following blocks
Flash Memory 1 : 8KB * 8blocks + 32KB * 62blocks
Flash Memory 2 : 32KB * 1block
Flash Memory 3 : 4KB * 8blocks




Block size with special meaning

1. Block size 1 is recognized as an area outside the subject of device function execution (processing skipped) in the programmer.

*In some control module, the setting of block size 1 above may not be effective. For details, refer to the manual of control module.

2. In some control module, the block size 100 is used to recognize the lock bit and target area for protect setting.

Applicable Control Module:
FL812,FL813,FL816,FL817,FL818,FL827,FL837,FR816,FR817,FR821,FR826
(Renesas M32R、M16C、M32C、R32C、RX Series)
