Setting excessive gain, phase or offset correction factors relative to the input signal can cause the datapath to overflow. To aid system debug, the QMC block contains built-in overflow detection and saturation blocks. These blocks generate flags which are connected to the IP interrupt mechanism using the datapath interrupt. The related interrupt flags for the QMC block are:
These interrupts can be enabled per converter channel.
- The gain correction multiplier range is between 0 and 2.0.
- The range of the phase correction multiplier is approximately ±26 degrees, or ±0.5 in terms of magnitude.
