MCP3564 not working with the same config as MCP3561

[mnemocron]

ADC value is always max value with MCP3564.

Example with MCP3564

• NOT working with MCP3564 (output code is always 3.3V)
• is my chip broken?
• what is working is:
  • correct register readback
  • IRQ is triggered for each conversion
• but each conversion just returns the max value

Is working on a different project. Maybe the chip was really broken.
