value of D6000 is judged as 101(hex), the ReqID is changed into 2 and D6250 is given a new
value 201(hex) and DVP-ES2-C sends out the request message again. By dong so, the
real-time reading can be realized. After reading succeeds, the data returning from the target
device are stored in D6000~D6005. The value of D6005: 100 （ hex） is the read value of P0-09.
