49.4.7.4 Sync error flag
The sync error flag, TCSR[SEF] or RCSR[SEF], is set when configured for an externally
generated frame sync and the external frame sync asserts when the transmitter or receiver
is busy with the previous frame. The external frame sync assertion is ignored and the
sync error flag is set. When the sync error flag is set, the transmitter or receiver continues
checking for frame sync assertion when idle or at the end of each frame.
The sync error flag can generate an interrupt only.
49.4.7.5 Word start flag
The word start flag is set at the start of the second bit clock for the selected word, as
configured by the Word Flag register field.
The word start flag can generate an interrupt only.
