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.

Unused words
The words used in the CPU Unit are set in the Unit Setup Area (DM 6601 to
DM 6604) as shown below. The input and output areas in the LR Area are allo-
cated in the order input area → output area starting from the first word of the LR
Area. The number of words in the areas are determined by the refresh settings.
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.

Note When LR Area bits are not being used for the above functions, they can be used
as work bits.
This area is used to manage the TIM, TIMH(15), TMHH(––), CNT, and
CNTR(12) instructions. The same numbers are used for timers and counters; do
not use the same number twice even for different instructions.
If TIM/CNT number is designated for word data, it will access the present value
(PV); if it is used for bit data, it will access the Completion Flag for the timer/
counter.
The Completion Flag turns ON when the PV of the timer/counter that is being
used goes to 0.
Interrupt processing is not performed for TIMH(15), i.e., timing processing is
performed only when the instructions is executed. If the cycle time is longer than
10 ms, counting may not be reliable.
