MISRA C:2012  Rule-16.4:  (Required)			Every switch statement shall have a default label

Amplification:

The switch-clause following the default label shall, prior to the terminating break statement, contain either:

• A statement, or
• A comment.

Example Code:

#include "misra.h"
#include "m3cmex.h"

extern int16_t rule_1604( void )
{
   int16_t x = 0;

   switch ( s16a )
   {
   case 0:
      x = 2;
      break;
   case 1:
      x = 1;
      break;
   }                            /* 2002 */

   return x;
}

QAC messages that encompass this guideline:

2002	No 'default' label found in this 'switch' statement.
