| mbed_official | 489:119543c9f674 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
| mbed_official | 489:119543c9f674 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
| mbed_official | 489:119543c9f674 | 17 | [..] |
| mbed_official | 489:119543c9f674 | 18 | The HAL contains two APIs' categories: |

| mbed_official | 489:119543c9f674 | 121 | configuration. It initializes the source of time base also when timeout |
| mbed_official | 489:119543c9f674 | 122 | is needed and the backup domain when enabled. |

| mbed_official | 489:119543c9f674 | 126 | (++) Systick timer is used by default as source of time base, but user |
| mbed_official | 489:119543c9f674 | 127 | can eventually implement his proper time base source (a general purpose |
| mbed_official | 489:119543c9f674 | 128 | timer for example or other time source), keeping in mind that Time base |
| mbed_official | 489:119543c9f674 | 129 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
| mbed_official | 489:119543c9f674 | 130 | handled in milliseconds basis. |
