Bits 7 to 5: Transmit Payload Type (TPT[2:0]) – These bits determines the value transmitted in the payload type
(third, fourth, and fifth bits in the MA byte).
Bit 4: Transmit Timing Source Indicator Bit Generation Disable (TTIGD) – When 0, the last three bits of the MA
byte (MA[6:8]) are generated from the four timing source indicator bits TTI[3:0]. When 1, TTI[3] is ignored and
TTI[2:0] are directly inserted into the last three bits of the MA byte.
Bits 3 to 0: Transmit Timing Source Indication (TTI[3:0]) – These four bits make up the timing source indicator
bits.
