01h
Illegal function
The function code is not supported.
02h
Illegal data address
Try to write an illegal register.
03h
Illegal data value
The quantity of registers is too large (>123).
04h
Server device failure
The accessed data includes the incomplete data.
For example, the host controller only writes 16 bits of
32-bits parameter.
The following table is an example of requesting to write the data of “00 0Ah” and “01 02h” into
2 registers, where the starting address is 0x0001.
