Payload Time Slot Bus Clock: This clock is usually based on SIB_TXHSCLK
timing on the Payload Time Slot Bus.
Clock Rate is 51.84 MHz (±20 ppm)
Payload Time Slot Bus Strobe: A strobe signal that indicates the start of a frame with 84 time
slots carrying payload data. The Strobe indicates the beginning of each Payload time slot Frame.
Payload Time Slot Bus Transmit Data: This is the serial payload data sent from the CX28500 to
the other device. This signal may be driven on the rising edge of TSB_CLK or on the falling edge,
according to the TDAT_EDGE bit in the TSIU Port Configuration Register.
