Specifying bit
addresses
The word and bit numbers are specified
directly to specify a bit (input bits).

Specifying word
addresses
The word number is specified directly to
specify the 16-bit word.
MOV 3 D200
Specifying offsets for bit
addresses
In brackets, specify the number of bits
to offset the specified starting bit
address.
A symbol can also be specified for the
starting bit address. Only Holding,
Work, DM, and EM Area addresses can
be used regardless of whether a physi-
cal address or symbol is used.
A constant or word address in I/O mem-
ory can be used for the offset. If a word
address is specified, the contents of the
word is used directly as the offset.
