Section 3-23
CPU Bus Unit:
8000 to 800F hex
(to specify unit numbers 0 to F hex)
S+1:
Number of words to transfer
(0001 to 0080 Hex, depends on Special I/O Unit or CPU Bus Unit)
Operand Specifications
Description
IORD(222) reads the number of words designated in S+1 from the memory
area of the Special I/O Unit or CPU Bus Unit whose unit number is designated
by S and outputs the data to D. Only Special I/O Units or CPU Bus Units
mounted on CPU Racks or Expansion I/O Racks can be designated. Refer to
the operation manual of the Special I/O Unit or CPU Bus Unit from which data
is being read for specific details for each Unit.
