inactive
RIC is activated if one of the S_STA bits RINF or ICV has changed.
inactive
A change in the received 4-bit Q-channel has been detected. The
new code can be read from the SQRx bits of registers SQRR within
the next multiframe
SQRR register.
inactive
The S channel data for the next multiframe is writable.
The register for the S bits to be transmitted has to be written within
the next multiframe. This bit is reset by writing register SQXR.
This timing signal is indicated with the start of every multiframe.
Data which is written right after SQW-indication will be transmitted
with the start of the following multiframe. Data which is written
before SQW-indication is transmitted in the multiframe which is
indicated by SQW.
SQW and SQC could be generated at the same time.
