Byte 03 – Parameter Length
The Parameter Length field indicates the length of the threshold or
cumulative value in bytes. For example, if the value requires two
bytes, you would specify 02h for this field. Table 8-3 lists the length of
each counter.

Note: You can specify any value from 0 to FFh for the Parameter
Length field. If you specify 0 for the Parameter Length, the
Parameter Value will be set to 0.
Bytes 04 to nn – Parameter Value
The Parameter Value field indicates either a new threshold value or a
new current cumulative value for the counter, depending on the
value you specified for PC in the CDB. The length of the value is
defined by the Parameter Length field.
If the parameter value you specify is shorter than the actual
length, the CTS pads the value with zeros from the parameter
length to the most significant byte. That is, if you specify 8h for
the parameter value and the length is two bytes, the CTS pads the
value to 0008h.
If the parameter value you specify is longer than the actual
length, all extra bytes between the actual length and the most
significant byte of the Parameter Value must be 0. That is, if the
length is two bytes, specifying FFFFFFh for the value would be an
error, specifying 00FFFFh would not.
You can specify any value for the parameter from 0 to all FFs.
