TXONT<6:0>: Transmitter Enable On Time Tick bits
Transmitter on time before beginning of packet. TXONT is a 9-bit value. The TXONT<8:7> bits are
located in PACON2<1:0>. Units: tick (50 ns). Default value = 0x028 (40 * 50 ns = 2 μs).
TICKP8: Symbol Period Tick bit
Number of ticks to define a symbol period. Tick period is based on the system clock frequency of
20 MHz. TICKP is a 9-bit value. The TICKP<7:0> bits are located in SYMTICKL<7:0>.
Units: tick (50 ns). Default value = 0x140 (320 * 50 ns = 16 μs).
TICKP<7:0>: Symbol Period Tick bits
Number of ticks to define a symbol period. Tick period is based on the system clock frequency of
20 MHz. TICKP is a 9-bit value. The TICKP8 bit is located in SYMTICKH<0>.
Units: tick (50 ns). Default value = 0x140 (320 * 50 ns = 16 μs).
