TURNTIME<3:0>: Turnaround Time bits
Transmission to reception and reception to transmission turnaround time. Refer to
IEEE 802.15.4™-2003 Standard, Table 18: PHY Constants and Section 7.5.6.4.2 “Acknowledgment”.
TURNTIME + RFSTBL = aTurnaroundTime = 12 symbols.
Units: symbol period (16 μs). Default value: 0x4. Minimum value: 0x2.
Recommended values: TURNTIME = 0x3 and RFSTBL = 0x9.
Reserved: Maintain as 0x8
