IF Conv. Mode
Selects the operational mode of the IF converter as:
00 - Disabled. Default mode which zeroes data into pipeline.
01 - Real x1. Real I outputs only, shifted by Fs/4.
10 - Real x2. Real samples output shifted by Fs/4. The sample on the I port is the first, earlier, sample of
the pair.
11 - Complex. Complex outputs shifted by Fs/4.

IF Conv. Status Clear
When set high, clears the IF Conv. status bits. Set low for normal operation and to allow the status bits
to update.
1
IF Conv. Bypass
When set high (default), bypasses the IF conv. stage. Set low for normal processing.
0
IF Conv. Reset
When set high, resets the IF conv. state machine. Set low (default) for normal operation.

I Channel Saturation
When high, indicates the IF conv. saturated at least one sample since the last control word 0x20, bit 2
command.
0
Q Channel Saturation
When high, indicates the IF conv. saturated at least one sample since the last control word 0x20, bit 2

Address Auto Increment
Set high to automatically increment coef/address after any access operation (read/write). Low (default) is
not auto increment.
3
Real Pipeline Select
Set high to configure the filter to process muxed real data, with the values arriving on the IIN<17:0> port
in serial fashion with I following Q. Set low (default) for complex operation.
2
Clear Status
Set high to clear all status bits, low for normal status bit updates.
1
Bypass
Set high (default) to bypass the correction filter, low to enable processing.
