AR bits are used for specific functions related to the operation of the Custom-
izable Counter Unit's special I/O. For details on the functions of individual bits,
refer to 6-4 AR Area.
This area can be used for data exchange with user-set words (in the CIO, WR,
AR, HR, DM, or EM Area) in the CPU Unit.

allocated in the order input area ® output area starting from the first word of

General-purpose I/O is exchanged between the LR Area and the user-set
words in the CPU Unit, as shown in the following table.
