| dudmuck | 335:b4678b054027 | 14 | [..] |
| dudmuck | 335:b4678b054027 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
| dudmuck | 335:b4678b054027 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
| dudmuck | 335:b4678b054027 | 17 | [..] |
| dudmuck | 335:b4678b054027 | 18 | The HAL contains two APIs' categories: |
| dudmuck | 335:b4678b054027 | 19 | (+) Common HAL APIs |
| dudmuck | 335:b4678b054027 | 20 | (+) Services HAL APIs |

| dudmuck | 335:b4678b054027 | 121 | configuration. It initializes the source of time base also when timeout |

| dudmuck | 335:b4678b054027 | 125 | Tick interrupt priority. |
| dudmuck | 335:b4678b054027 | 126 | (++) Systick timer is used by default as source of time base, but user |
| dudmuck | 335:b4678b054027 | 127 | can eventually implement his proper time base source (a general purpose |
| dudmuck | 335:b4678b054027 | 128 | timer for example or other time source), keeping in mind that Time base |
| dudmuck | 335:b4678b054027 | 129 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
