(1) The GPIOs P1.0, P1.1, P1.3, P1.4, P2.6, and P2.7 are implemented but not available on the device pinout. To avoid floating inputs,

these digital I/Os should be properly configured. The pullup or pulldown resistors of the unbounded P1.x GPIOs should be enabled, and

the VLO should be selected as the ACLK source (see the MSP430x2xx Family User's Guide (SLAU144)).
