Error code and exception code
If a slave receives the request without a communication error, but cannot handle
it, the slave will return an exception response which includes error code and ex-
ception code informing the master of the nature of the error. The error code is
formed by setting the MSB of the function code to 1 (i.e. function code plus
with 0x80, like 0x83, 0x86, 0x90, 0x97), then the exception response has a for-
mat shown below.
Slave No.
