• If the host writes an invalid register (a non-existing parameter or a read only
parameter), the value will be ignored and no error response will be made.
However, the current value will not reflect the desired new value.
• If the host writes a read only register, then the value will be ignored and no error
response will be made. However, the current value will not reflect the desired new
value.
• If P000 is activated, then the value will be ignored and no error response will be
made. However, the current value will not reflect the desired new value.
• If the host attempts to write one or more registers that are out of range, an
exception response code 2 or 3 is generated depending if the start address is valid.
• If the host attempts to read one or more registers that are out of range, an
exception response code of 2 or 3 is generated.
• If the host used an unsupported function code, an exception response code of 01
should be generated. However, this is not guaranteed and there may be no
response.
