| 5 | Description: |
| 6 | By default (value '0'), the capture thread checks for the Conversion |
| 7 | Ready Flag to being set prior to committing a new value to the sample |
| 8 | buffer. This synchronizes the in-chip conversion rate with the |
| 9 | in-driver readout rate at the cost of an additional register read. |
| 10 | |
| 11 | Writing '1' will remove the polling for the Conversion Ready Flags to |
| 12 | save the additional i2c transaction, which will improve the bandwidth |
| 13 | available for reading data. However, samples can be occasionally skipped |
| 14 | or repeated, depending on the beat between the capture and conversion |
| 15 | rates. |

| 21 | Description: |
| 22 | The value of the shunt resistor may be known only at runtime fom an |
| 23 | eeprom content read by a client application. This attribute allows to |
| 24 | set its value in ohms. |
