Can AD9371 support RX ADC IQ swap by setting ADC/sample crossbar?

Question

From JESD204B Framer API Data Structures of AD9371-User-Guide-UG-992.pdf, we only found "serializerLaneCrossbar" setting, no "ADC/SAMPLE crossbar setting. Could current AD9371 API support ADC/SAMPLE CROSSBAR swap setting?

You can refer following code snippet in API function MYKONOS_setupJesd204bFramer() in 'mykonos.c' to understand how to set ADC crossbar. #define MYKONOS_ADDR_FRAMER_ADC_XBAR_SEL 0x061 mykonosErr_t MYKONOS_setupJesd204bFramer(mykonosDevice_t *device) { : : : framerADC_XBar = 0xB1; if (ML == 24) { if (device->rx->rxChannels == RX1) { /* adc 0 and 2 used */ framerADC_XBar = ((framerADC_XBar & 0x0C) << 2) | (framerADC_XBar & 0x03); } else if (device->rx->rxChannels == RX2) { /* swap ADC xbar for Rx1 and Rx2 */ framerADC_XBar = ((framerADC_XBar & 0xF) << 4) | ((framerADC_XBar & 0xF0) >> 4); /* adc 0 and 2 used */ framerADC_XBar = ((framerADC_XBar & 0x0C) << 2) | (framerADC_XBar & 0x03); } /* Framer: Set ADC Crossbar */ CMB_SPIWriteByte(device->spiSettings, MYKONOS_ADDR_FRAMER_ADC_XBAR_SEL, framerADC_XBar); } else { /* Framer: Set ADC Crossbar */ CMB_SPIWriteByte(device->spiSettings, MYKONOS_ADDR_FRAMER_ADC_XBAR_SEL, framerADC_XBar); } : : : }
