3-6-6 Special I/O Unit Area Settings
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.
Setting
Mode
Function
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.
