9.10.3 Digital I/O

Two 8-bit I/O ports (P1 and P2) are implemented on the MSP430i204x, MSP430i203x, MSP430i202x devices. On 32-pin RHB devices, ports P1 and P2 are complete, and 16 I/Os are available. On 28-pin PW devices, port P2 is reduced to 4 bits, and 12 I/Os are available. On 28-pin PW devices, the unavailable pins (P2.4 to P2.7) must be programmed to port function, output direction, and be driven with value 0.

  • All individual I/O bits are independently programmable.
  • Any combination of input, output, and interrupt condition is possible.
  • Edge-selectable interrupt input capability for all 8 bits of port P1 and P2
  • LPM4.5 wake-up capability for Port pins P2.1 and P2.2
  • Read and write access to port-control registers is supported by all instructions.
