This procedure applies to devices with embedded software. White box testing, sometimes known as X‐ray or software structural testing, is a detailed evaluation of how well the software operates internally during actual operation, which may be under either real‐time or individual instruction stepping operating conditions. Example of internal software items and functions to be evaluated are:

 Memory management functions and memory integrity

 Interrupt operation and prioritization performance

 Worst‐case stack depth penetration

 Power on initialization, shutdown, and reset performance

 Critical code timing performance

 I/O handling and data conversion

 Calibration variables functionality
