Description
ADC Clock Disable
0 : Clock enabled when ADC enabled
1 : Clock disabled, even if ADC is enabled
Read the current ADC I-branch value.
Reserved, write as 0.
Read the current ADC Q-branch value.
Description
Reserved, write as 0.
The TX DACs data source is selected by DAC_SRC according
to:
0: Normal operation (from modulator).
1: The DAC_I_O and DAC_Q_O override values below.-
2: From ADC, most significant bits
3: I/Q after digital downmixing and channel filtering.
4: Full-spectrum White Noise (from CRC)
5: From ADC, least significant bits
6: RSSI / Cordic Magnitude Output
7: HSSD module.
This feature will often require the DACs to be manually turned on
in MANOR and TOPTST.ATESTMOD_MODE=4.
I-branch DAC override value.
Q-branch DAC override value.
