Legend:
R = Readable bit
-n = Value at POR
r = reserved
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 6
bit 5-2
bit 1-0
FIFOEN: FIFO Enable bit
1 = Enabled (default). Always maintain this bit as a ‘1’.
Reserved: Maintain as ‘0’
TXONTS<3:0>: Transmitter Enable On Time Symbol bits⁽¹⁾
Transmitter on time before beginning of packet. Units: symbol period (16 μs).
Minimum value: 0x1. Default value: 0x2 (2 * 16 μs = 32 μs). Recommended value: 0x6 (6 * 16 μs = 96 μs).
TXONT<8:7>: Transmitter Enable On Time Tick bits⁽¹⁾
Transmitter on time before beginning of packet. TXONT is a 9-bit value. TXONT<6:0> bits are located
in SYMTICKH<7:1>. Units: tick (50 ns). Default value = 0x028 (40 * 50 ns = 2 μs).
Note 1: Refer to Figure 4-4 for timing diagram.
