9.5.1.5 TimeSlotPeriod
When sending I-CODE1 Quit frames, it is necessary to generate the exact chronological
relationship to the start of the command frame.
If at the end of command execution TimeSlotPeriod > 0, the TimeSlotPeriod starts. If the
FIFO buffer contains data when the end of TimeSlotPeriod is reached, the data is sent. If
the FIFO buffer is empty nothing happens. As long as the TimeSlotPeriod is > 0, the
TimeSlotPeriod counter automatically starts on reaching the end.
This forms the exact time relationship between the start and finish of the command frame
used to generate and send I-CODE1 Quit frames.
When the TimeSlotPeriod > 0, the next Frame starts with exactly the same interval
TimeSlotPeriod/CoderRate delayed after each previous send frame. CoderRate defines
the clock frequency of the encoder. If TimeSlotPeriod[7:0] = 0, the send function is not
automatically triggered.
The content of the TimeSlotPeriod register can be changed while it is running but the
change is only effective after the next TimeSlotPeriod restart.
Example:
Remark: The TimeSlotPeriodMSB bit is contained in the MFOUTSelect register.
Table 23.
Remark: Set bit TxCRCEn to logic 0 before the Quit frame is sent. If TxCRCEn is not set
to logic 0, the Quit frame is sent with a calculated CRC value. Use the CRC8 algorithm to
calculate the Quit value.
