Counter (C)
A decrement counter detects the rising edge of the counter input when the Counter
instruction is executed and updates the current value. When the current value reaches
0, count up is said to occur. At this time, the Count-Up relay of the counter turns on.
When the reset input is on, the counter does not accept count input.

Data Register (D)
Data registers are memory which store computation results of the program, and one
point consists of 16-bits. Data can be read/written on 16-bit on 32-bit basis using
application instructions.
When you use the data registers on a 32-bit basis, lower 16-bit data is stored in a data
register having a data register number you specified, and upper 16-bit data is stored in a
data register having the data register number you specified plus 1.

Note: When upper data of BCD code is $0123 and lower data is $4567,
the lower data is stored in D0002 and the upper data in D0003.
