Bits 6 to 4: Receive Payload Type (RPT[2:0]) – These three bits are the integrated version of the payload type
(MA[3:5]) from the MA byte.
Bits 3 to 0: Receive Timing Source Indication (TI[3:0]) – When timing source indicator extraction is enabled,
these four bits are the integrated version of the four timing source indicator bits extracted from the last three bits of
the MA byte (MA[6:8]). When timing source indicator bit extraction is disabled, TI[3] is zero, and TI[2:0] contain the
integrated version of the last three bits of the MA byte.
