I believe that the first reference to the Advance Credit message should
be Advance Credit *(Received)* message like it is in the second case:
126.96.36.199 SSP_TCM (transmit frame credit monitor) state machine
The SSP_TCM state machine’s function is to ensure that transmit SSP frame
credit is available before a frame is transmitted. This state machine
consists of one state.
This state machine shall keep track of the number of transmit SSP frame
*If an Advance Credit message is received*, then this state machine shall:
1) increment transmit SSP frame credit by one frame;
2) ignore the first RRDY Received message received; and
3) add one transmit SSP frame credit for each subsequent RRDY Received
*If an Advance Credit (Received) message is not received*, then this state
machine shall add one transmit SSP frame credit for each RRDY Received
