    As per documentation, conversion (sync) clock can go high during clocking-out of data, so length is not an issue, as long is is longer than 1 bit clock.

    If the chip is wired as in datasheet or in similar fashion why do you bother with SPI? use I2S it is easier and runs continuously. I have done that with other chips with similar SPI-type connection Note, it says...

    You can use standard SAI (stereo protocol) where frame-sync toggles every 16 bit. data will be converted and transferred at alternate frame-sync phases. In fact, I used 2 ADS8881 where frame-sync to second ADC was...

    I know, the datasheet says SPI-compatible, but I would try to use SAI/TDM and use frame-sync for conversion. I have done that in the past for TI ADS series.

    Yes, when put into hibernate state all MCU but RTC is shut down. This includes USB and as I discovered during this test it "disables" the bootloader. In other words if in hibernate state, pressing program button does...

    So far, I have no issue with the following test program #define SNVS_LPCR_LPTA_EN_MASK (0x2U) void hibernate(uint32_t nsec) { uint32_t tmp = SNVS_LPCR; // save control register SNVS_LPSR |= 1;...
