SL RC400
Example:
CoderRate = 0x05 (~52.97kHz)
For I•CODE1 standard mode the interval should be 8.458ms
->TimeSlotPeriod = CoderRate * interval = 52.97kHz * 8.458ms –1 = 447 (447 = 0x1BF)
Note: The MSB of the TimeSlotPeriod is in the SIGOUTSelect register see 5.2.5.7

Note: The MSB of the TimeSlotPeriod is in the SIGOUTSelect register see 5.2.5.7
Note: It is strictly recommended that bit TxCRCEn is set to 0 (see 5.2.5.3) before the Quit-Frame is sent. If
the TxCRCEn is not set to 0 a CRC value is calculated and sent with the Quit-Frame.
To calculate the Quit value a CRC8 algorithm has to be used.
