+ +Channel modes +^^^^^^^^^^^^^ + +* **Mode A** - First set of filter and decimation settings +* **Mode B** - Second set of filter and decimation settings + +The hardware provides two mode profiles (A and B), each holding one +(frequency, filter) combination. When buffered capture is started, +enabled channels are grouped by their configured (frequency, filter) +pair. Up to two distinct groups are supported; the driver automatically +assigns each group to a mode slot and programs the hardware accordingly.
Say what happens if the user tries to use more sets of settings and hence two groups isn't enough. -- Jonathan Cameron [off-list ref]
