* 2: Specification of duty (specify using K constant)
If the control code is K0 to K19, the duty is K0 to K999 (0.0% to 99.9%).
If the control code is K20 to K24, the duty is K0 to K990 (0% to 99%).
Values are specified in units of 1% (K10) (digits below the decimal point are rounded off).
Note
If a value outside the specified range is written for the duty area
while the instruction is being executed, the frequency that is
output will be uncorrected. Written data is not corrected,
however.
