PSI5 transmission modes and time slots. Accepted time slot values are 0.5 μs to 511.5 μs in 0.5 μs increments. Care must be
taken to prevent from programming time slots which violate the PSI5 Version 1.3 specification, or time slots which will cause data
contention.
Note: TIMESLOTB is only used for Synchronous Double Sample Rate Mode and 16-Bit Resolution Mode.
