PAONT<7:0>: Power Amplifier Enable On Time Tick bits⁽¹⁾
Power amplifier on time before beginning of packet. PAONT is a 9-bit value. The PAONT8 bit is located
in PACON1<0>. Units: tick (50 ns). Default value = 0x029 (41 * 50 ns = 2.05 μs).
Note 1: Refer to Figure 4-4 for timing diagram.

PAONTS<3:0>: Power Amplifier Enable On Time Symbol bits⁽¹⁾
Power amplifier on time before beginning of packet. Units: symbol period (16 μs).
Minimum value: 0x1 (default) (1 * 16 μs = 16 μs).
PAONT8: Power Amplifier Enable On Time Tick bit⁽¹⁾
Power amplifier on time before beginning of packet. PAONT is a 9-bit value. The PAONT<7:0> bits are
located in PACON0<7:0>. Units: tick (50 ns). Default value = 0x029 (41 * 50 ns = 2.05 μs).
Note 1: Refer to Figure 4-4 for timing diagram.
