Physical-layer data indication (PDAI)
When promiscuous mode is set, (refer to MSTR command), no address filtering is applied and all
received packets are intercepted at the PHY level and converted direct to PDAI messages. The FCS
(checksum) field will have been already verified and, contrary to the IEEE 802.15.4 specification, the
first and second bytes of the FCS field will contain CC2420-defined RSSI and LQI values.

Transmit options:
Source PAN ID
Source addressing mode (0x02 = short, 0x03 = long)
Destination addressing mode (0x02 = short, 0x03 = long)
Source address. (If SrcAddrMode specifies short addresses,
ignore last 6 bytes.)
Destination address. (If DstAddrMode specifies short addresses,
ignore last 6 bytes.)
Destination PAN ID
Data handle. (Ignored; the current macDSN value is used and
then incremented.)
Payload to be transmitted
Bit 0 = acknowledged transmission
Bit 1 = GTS transmission
Bit 2 = indirect transmission
Bit 3 = security enabled transmission.
