| * Test timer accuracy |
| * |
| * After sync, DUT and TH start counting down one second. After one second, |
| * DUT raises GPIO level, which triggers an interrupt on TH. TH determines |
| * whether the test passes or not based on how much more or less time elapsed |
| * than one second. |
| * |
| * Requirements: |
| * - Sync connection |
| * - GPIO_OUTPUT connection for sending notification from DUT |
| * - Calibrated TH timer |
