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.
