Counter Reset
[39, 40]
Notes:
39.CE
= BE0 – BE1 = LOW; CE
= MRST = CNT/MSK = HIGH.
40.No dead cycle exists during counter reset. A Read or Write cycle may be coincidental with the counter reset.
41.Retransmit happens if the counter remains in increment mode after it wraps to initially loaded value.
