/* MY_IAR, MY_TI, and MY_GCC are here to ease further compilation conditionals.
 * Remember that a lot of non-gcc compilers also define __GNUC__ so
 * directly testing against that is not a good idea.
 *
 * The SV() macro stands for "State Value".
 * It is used to create enum values latter used in switches with in_range.
 * in_range expands to __even_in_range when supported, in which case
 * the values should be even.
 * GCC seems happier with consecutive values.
 *
 * MASK_MISRA and UNMASK_MISRA are used to temporarily disable MISRA rules
 * checking that is provided by TI MSP430 Optimizing C compiler.
