---|---|---|---|---|
7:6 | FL_REF_EN[1:0] | R/W | 0h | Reference monitor configuration Enables and configures the reference monitor. 00 : Disabled (default)01 : FL_REF_L0 monitor enabled, threshold 0.3 V 10 : FL_REF_L0 and FL_REF_L1 monitors enabled, thresholds 0.3 V and 1/3 · (AVDD – AVSS) 11 : FL_REF_L0 monitor and 10-MΩ pull-together enabled, threshold 0.3 V |
5 | REFP_BUF | R/W | 0h | Positive reference buffer bypass Disables the positive reference buffer. Recommended when V(REFPx) is close to AVDD. 0 : Enabled (default)1 : Disabled |
4 | REFN_BUF | R/W | 1h | Negative reference buffer bypass Disables the negative reference buffer. Recommended when V(REFNx) is close to AVSS. 0 : Enabled1 : Disabled (default) |
3:2 | REFSEL[1:0] | R/W | 0h | Reference input selection Selects the reference input source for the ADC. 00 : REFP0, REFN0 (default)01 : REFP1, REFN1 10 : Internal 2.5-V reference(1) 11 : Reserved |
1:0 | REFCON[1:0] | R/W | 0h | Internal voltage reference configuration(2) Configures the behavior of the internal voltage reference. 00 : Internal reference off (default)01 : Internal reference on, but powers down in power-down mode 10 : Internal reference is always on, even in power-down mode 11 : Reserved |
