Dear Sir/Madam,
I am using FMC176 board of 4DSP. When I look at the file FMC176_adc.cpp, I can't not figure out the absolute address of the registers that following commands what to execute, especially the first address [size=78%]bar_adc_phy+0x00.[/size]
// JESD204B Lane Configuration
rc = sipif_writesipreg(bar_adc_phy+0x00, 0x82); Sleep(10);
rc = sipif_writesipreg(bar_adc_phy+0x01, 0x01); Sleep(10); //F=2
rc = sipif_writesipreg(bar_adc_phy+0x03, 0x1F); Sleep(10); //K=32
My understanding is that these commands configure the JESD204b receiver on the FPGA with 2 octets/frame and 32 frames/multiframe. But I cannot work out what the first command will do because it does not have an included comment.
Could you please advise?
Thanks,
