* The CAT1 WDT is only capable of supporting certain timeout ranges below its maximum timeout.
* As a result, any unsupported timeouts given to the HAL WDT are rounded up to the nearest supported value.
* The following table describes the unsupported ranges and the timeout values they are rounded to.
*
* <table class="doxtable">
*   <tr><th>Range (ms)</th><th>Rounded Timeout (ms)</th></tr>
*   <tr>
*     <td>3001 - 3999</td>
*     <td>4000</td>
*   </tr>
*   <tr>
*     <td>1501 - 1999</td>
