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 87:085cde657901 18 The HAL contains two APIs categories:
mbed_official 87:085cde657901 19 (+) Common HAL APIs
mbed_official 87:085cde657901 20 (+) Services HAL APIs
