Note For Timer Completion Flags and Counter Completion Flags, there is no distinction between word addresses and bit
addresses.
The following table shows the data formats that the CP1E CPU Units can handle.

Specifying
indirect DM
addresses in
Binary Mode
An offset from the beginning of the DM Area
is specified. The contents of the address will
be treated as binary data (E-type CPU Unit
0000 to 2047, N/NA-type CPU Unit 0000 to
8191) to specify the word address in DM
Area.
Add the @ symbol at the front to specify an
indirect address in Binary Mode.
MOV #0001 @D300
Specifying
indirect DM
Addresses
in BCD
Mode
An offset from the beginning of the DM Area
is specified. The contents of the address will
be treated as BCD data (E-type CPU Unit
0000 to 2047, N/NA-type CPU Unit 0000 to
8191) to specify the word address in the DM
Area.
Add an asterisk (*) at the front to specify an
indirect address in BCD Mode.
MOV #0001 *D200

The data is treated as 16-bit signed binary data using the leftmost bit as the
sign bit. The value is expressed in 4-digit hexadecimal.
Positive numbers: If the leftmost bit is OFF, it indicates a non-negative value.
For 4-digit hexadecimal, the value will be 0000 to 7FFF hex.
Negative numbers: If the leftmost bit is ON, it indicates a negative value. For 4-
digit hexadecimal, the value be 8000 to FFFF hex. It will be expressed as the
2’s complement of the absolute value of the negative value (decimal).
