REC Configuration Register

The REC Configuration Register determines whether Resistance Error Correction is used for each

external diode channel.

Bit 2 - REC3 - Controls the Resistance Error Correction functionality of External Diode 3



‘0’ - the REC functionality for External Diode 3 is disabled



‘1’ (default) - the REC functionality for External Diode 3 is enabled.

Bit 1 - REC2 - Controls the Resistance Error Correction functionality of External Diode 2.



‘0’ - the REC functionality for External Diode 2 is disabled



‘1’ (default) - the REC functionality for External Diode 2 is enabled.

Bit 0 - REC1 - Indicates the Resistance Error Correction functionality of External Diode 1. If External

Diode 1 is selected as the hardware shutdown channel then this bit is read only.



‘0’ - the REC functionality for External Diode 1 is disabled



‘1’ (default) - the REC functionality for External Diode 1 is enabled.

The REC Configuration Register is software locked.
