AFE7950EVM: How to disable both ADC_JESD blocks using python in Latte?

Hi,

I am running a static test using the AFE7950EVM, without the TSW14J56, by starting with the script AFE79xx_repeater_Mode5.py in Latte. This particular script configures the system for JESD Rx > Tx loopback.

I my case, I want to turn OFF or disable all JESD Rx channels and simply send a constant value out of the DAC. I can do the latter using the code snippet below. But the Rx lanes are still enabled, how do I disable them so the EVM is only enabled as a transmitter?

Thanks in advance

for i in [0,1]:

      AFE.JESD.DACJESD[i].dacJesdConstantTestPatternValue(1,j,0,16384,0) # enable, channelNum, bandNum, Ival, Qval
