 *
 *  In order to access the TimerB0 clock input the port mapping value must be
 *  set to 1 (see Table 9 of the MSP430F551x,MSP430F552x datasheet).  In this
 *  example the TB0CLK/CBOUT function is ported to pin 4.7.
 *
 *  Some MSP430 devices allow the digital IO to be driven from a different
 *  voltage rail (DVIO) than the voltage rail (VCC) that the Comp_B peripheral
 *  uses.  If the comparator output, CBOUT, uses DVIO and DVIO is different
 *  from VCC, then the input high and input low values set within the library
 *  need to be updated.  These values are set in the Comp_B control register 2,
 *  CBCTL2, found in the CTS_HAL.c file.
 *
 *  The element and sensor definitions found in the configuration file
 *  structure.c use designated initializer lists. This allows members to be
 *  initialized in any order and also enhances the readability of the element
 *  being initialized.
 *  This feature requires the GCC language extension found in Code Composer
 *  Studio (CCS).  C99 is the default dialect found in IAR and therefore the
 *  default settings can be used.
