The REC Configuration Register determines whether Resistance Error Correction is used for each  
external diode channel. The REC Configuration Register is software locked.  
Bit 2 - REC3 - Controls the Resistive Error Correction functionality of External Diode 3 and External  
Diode 4 (if APD is enabled, see Section 6.9)  
„
„
‘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 Resistive 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 - Controls the Resistive Error Correction functionality of External Diode 1. This bit is  
locked if the SHDN_SEL pin is not pulled to VDD (see Table 6.1).  
„
„
‘0’ - the REC functionality for External Diode 1 is disabled  
‘1’ (default) - the REC functionality for External Diode 1 is enabled.
