Control synchronous bitstream I/O.
Only valid on ASI4346 adapters.
|hpi_err_t HPI_Bitstream_GetActivity||(||const hpi_hsubsys_t *||phSubSys,|
Returns 2 indicative measurements of the incoming data stream.
The clock input is deemed inactive if no data bytes are received within a certain number of calls to a polling routine. The time this takes varies according to the number of active streams. If there is clock activity, the data activity indicator is a sample of 16 bits from the incoming data. If this is persistently 0 or 0xFFFF, this may indicate that the data input is inactive.
|phSubSys||Vestigial subsys handle (unused), may be set to NULL|
|hControl||Handle to bitstream control|
|pwClkActivity||1==clock is active, 0==clock is inactive|
|pwDataActivity||1 word sampled from the incoming raw data|
