Description:
If the device receives a function code other than 03H, 06H,
or 10H, the abnormal response code 01H will be returned.
In order to protect the important parameters of the device
from being damaged, some registers only support users’
reading operation (03H function code). If these registers
are written (06H, 10H function code), the abnormal
response code 02H will be returned.
The operation data section only supports writing
operations (06H, 10H function code). If these registers are
read (03H power code), the abnormal response code 02H
will be returned.
Read/write operations on addresses beyond the range of
the offset address allocation table will return the abnormal
response code 02H.
In order to prevent some registers from writing illegal
parameters, when the registers in the user data area are
written (06H, 10H function code), the device will verify the
