Loads filter coefficients (FC's) from memory buffer onto tuner chip
Function PIC_LOADFC - Loads filter coefficients (FC's) from memory buffer onto tuner chip
PIC p Handle to Device
int port Tuner port number
short data[] Array of shorts containing the filter coefficients
int ndata Number of 16 bit words in data[]
int flags Run-time modifiers
Loads filter coefficients into the tuner port. If the filter has non-unity gain, the user
must reset the GAIN after loading the coefficients. Use PIC_SETKEY with KEY_GAIN.
If the card will be using a non-default CPC value, make sure to set the CPC=x flag to the same
value while loading filters as while running to ensure that ganged channels are setup properly.
Note: The CFIR and PFIR tuner filters will normally be half band (or less) because the filters
decimate by two in the output stage. However, when using CPC=1 with a graychip 4016, the PFIR
output is not decimated so the filter should be based on the actual output rate. See the
graychip datasheet for more info.
