Function and operation explanation
1. 32-bit operation (DHSCR)
When the current value of the high speed counter of the device specified by becomes the comparison
value of the device specified by (for example, when the current value changes from "199" to "200" or
from "201" to "200" if the comparison value is K200), the bit device specified by is reset (set to OFF)
regardless of the operation cycle. In this instruction, the comparison processing is executed after the counting
processing in the high speed counter.
Operation
When the current value of the high speed counter C255 changes (counts) from "99" to "100" or from "101" to
"100", Y010 is reset (output refresh).
