Note During a period of a total of 11 bits, 3 bits of interframe space and 8 bits of suspend transmission, the
Cautions 1. Execute transmission abort processing by clearing the TRQ bit, not the RDY bit.
transmission request may have already been acknowledged by the protocol layer.
transmission may not be aborted but started even if the TRQ bit is cleared.
2. Before making a sleep mode transition request, confirm that there is no transmission
