| mbed_official | 87:085cde657901 | 14 | [..] |
| mbed_official | 87:085cde657901 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
| mbed_official | 87:085cde657901 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
| mbed_official | 87:085cde657901 | 17 | [..] |
| mbed_official | 226:b062af740e40 | 18 | The HAL contains two APIs' categories: |
| mbed_official | 87:085cde657901 | 19 | (+) Common HAL APIs |
| mbed_official | 87:085cde657901 | 20 | (+) Services HAL APIs |

| mbed_official | 87:085cde657901 | 126 | configuration. It initializes the systick also when timeout is needed |
| mbed_official | 87:085cde657901 | 127 | and the backup domain when enabled. |

| mbed_official | 226:b062af740e40 | 131 | (++) Systick timer is used by default as source of time base, but user |
| mbed_official | 226:b062af740e40 | 132 | can eventually implement his proper time base source (a general purpose |
| mbed_official | 226:b062af740e40 | 133 | timer for example or other time source), keeping in mind that Time base |
| mbed_official | 226:b062af740e40 | 134 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
| mbed_official | 226:b062af740e40 | 135 | handled in milliseconds basis. |

| mbed_official | 226:b062af740e40 | 142 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
| mbed_official | 226:b062af740e40 | 143 | ISR process will be blocked. |
