hi, The usability of the pins available in the 16 pin-extension has been discussed earlier in this thread. I seek a few clarifications: 1) Pins connected to Port1 or Port2 of the MSP430 can only be used as interrupt pins directly. Pins belonging to other Ports[3...6] can be used as interrupts by emulating them using Capture interface. Right? 2) Addressability of pins. For. example, take pin 7 of the 10-pin Extension. It can act as a GPIO or ADC. Namely, P2.1 or P6.2. Do i have to explicitly state somewhere in the code, for it to be recognized as a GPIO and not as an ADC?
