We are using the 80-pin package of MSP430F2617 (Rev H silicon) and we are unable to use the GPIO registers to control the state of P2.0 (pin 20) or P2.1 (pin 21). We have confirmed this behavior on multiple boards.
For example, the voltage of P2.0 (pin 20) remains at ~0V even when we set the P2 registers as follows:
P2REN = 0x00
P2SEL = 0x00
P2DIR = 0x01
P2OUT = 0x01
We confirmed that we can control other port 2 pins in this way. For example when we use similar settings on bit 3, we observe ~VDD at P2.3 (pin 23).
We have also confirmed that the CAPD register bits and the P2CAx register bits are all 0.
Is there some other register besides the ones listed that control P2.0 and P2.1 gpio function? This is a mature device so I'm sure this has been answered before but I couldn't find anything on E2E.
