What is the sequence for switching between channels whan you don't have access to the DRDY pin
I have read the FAQs Serial interface.
write 0x38, then monitor DRDY pin, then read 16 bits of data when it goes low.
write 0x39, then monitor DRDY pin, then read 16 bits of data when it goes low
After writing 0x38, I have to then read the communications register to get the DRDY bit value, but the adc is expecting 16 serial clocks for the data read. And if DRDY is high, I am not supposed to read the 16 bits of data anyway.
Just to make it a bit more difficult,CS is permanently tied low as well
