Auxiliary register for
operation
The divided remainder (16-bit) is stored in
DT9015/DT90015 when F32(%) or F52(B%)
instruction is executed.
The divided remainder (32-bit) is stored in

2.5 ms ring counter
The data stored here is increased by one every
2.5 ms. (H0 to HFFFF)
Difference between the values of the two points
(absolute value) x 2.5 ms = Elapsed time
between the two points.
