Other Parts Discussed in Thread: ADC3644
Hello,
I am bringing up the ADC3644 in its default configuration and operating it in 14-bit, 2-wire output mode as defined in the datasheet. As part of initial bring-up and interface verification, I would like to use the internal test pattern functionality to generate known and deterministic output data.
While the datasheet describes the relevant registers, the details around test pattern configuration and the resulting output format in 14-bit 2-wire mode are somewhat confusing, making it difficult to correlate register settings with expected output behavior.
I am looking for guidance on the appropriate values for registers 0x14, 0x15, and 0x16 (Test Pattern Registers) that will produce well-defined test patterns in this mode, along with the corresponding expected 14-bit output sequences on the data bus. This information would allow me to confirm correct SPI programming, output formatting, and data capture logic.
Thank you for your support.
Regards,
Fenil
