Clock Rate is 51.84 Mbps (±20 ppm)
84 time slots carrying payload data. The Strobe indicates the beginning of each
Payload time slot Frame.
Payload Time Slot Bus Transmit Data: This is the serial payload data to be received by
TSBUS. This signal is sampled on the rising edge of TSB_CLK.
must be transmitted in place of the data byte arriving 8 time slots later.
transmitted from TBUS on the rising edge of TSB_CLK.
TSB_RDAT is not valid data. TSB_RDAT is stuffed with all 1s.
