NOTE: Analog signals applied to digital gates can cause current flow from the positive to the negative terminal. The throughput current flows if the analog signal is in the range of transitions 0 →1 or 1→0. The value of the throughput current depends on the driving capability of the gate. For MSP430, it is approximately 100 μA. Use P6SEL.x=1 to prevent throughput current. P6SEL.x should be set, even if the signal at the pin is not being used by the ADC12. PnSel.x PnDIR.x Dir. Control From Module PnOUT.x Module X OUT PnIN.x Module X IN P6Sel.0 P6DIR.0 P6DIR.0 P6OUT.0 DVSS P6IN.0 unused P6Sel.1 P6DIR.1 P6DIR.1 P6OUT.1 DVSS P6IN.1 unused P6Sel.2 P6DIR.2 P6DIR.2 P6OUT.2 DVSS P6IN.2 unused P6Sel.3 P6DIR.3 P6DIR.3 P6OUT.3 DVSS P6IN.3 unused P6Sel.4 P6DIR.4 P6DIR.4 P6OUT.4 DVSS P6IN.4 unused P6Sel.5 P6DIR.5 P6DIR.5 P6OUT.5 DVSS P6IN.5 unused P6Sel.6 P6DIR.6 P6DIR.6 P6OUT.6 DVSS P6IN.6 unused NOTE: The signal at pins P6.x/Ax is used by the 12-bit ADC module. |
