configure the device
The device can be configured by writing to control registers CR0 and CR1. A read register is carried out by
auto-sequence when the device is put into the software power-down state. CR0 is read first and then CR1 at
the next two RD rising edges after the device is in the software power-down state. The falling edge of RD has
no meaning and does not trigger a conversion in the software power-down state.
