This response contains a timestamp that is 60 seconds after the previous response, and tag
has different data.
Note that the “Instance Counter” in the CBx response increments for each response.
The Master can see that
Bit 0
of the
IBCB & IBDCB
has been toggled, so it knows that a
new response in the Input Buffer is ready.
