Hi Support, in our MSP430F2xx UG we states 19.2.6 Comparator_A+, Port Disable Register CAPD The comparator input and output functions are multiplexed with the associated I/O port pins, which are digital CMOS gates. When analog signals are applied to digital CMOS gates, parasitic current can flow from V to GND. This parasitic current occurs if the input voltage is near the transition level of the gate. Disabling the port pin buffer eliminates the parasitic current flow and therefore reduces overall current consumption. CC The CAPDx bits, when set, disable the corresponding P2 input and output buffers as shown in Figure 19--4. When current consumption is critical, any port pin connected to analog signals should be disabled with its CAPDx bit. Where differently DS is not reporting any specific instruction on how to handle CAPDx register in order to reduce power consmption on analog port. Is it correct to disble input buffer through CAPDx register in order to reduce power consumption? Thanks and regards, Alberto
