The setting in bits 08 through 15 of DM 6602 determines the size and location of
the Special I/O Unit Area, as shown in the following table.

00

C200H-compatible
RAM Mode

DM 1000 through DM 2599 are used for the Special I/O Unit Area.

•

Data in the Special I/O Unit Area can be read/written.

•

The data cannot be converted to ROM.

01

C200H-compatible
ROM Mode 1

The contents of DM 7000 through DM 7999 are transferred to DM 1000 through DM 1999
at startup and DM 1000 through DM 1999 are used for the Special I/O Unit Area.

•

The UM Area Allocation operation must be performed beforehand.

•

The data is compatible with C200H applications that use EEPROM/EPROM.

•

ROM conversion is possible indirectly by converting DM 7000 through DM 7999 to ROM.

02

DM Linear Mode 1

DM 7000 through DM 7999 are used for the Special I/O Unit Area.

•

The UM Area Allocation operation must be performed beforehand.

•

DM 1000 through DM 1999 can be used as regular DM.

•

DM 7000 through DM 7999 can be converted to ROM.
