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.
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.
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.
• 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.
