This module provides the required Ambiq Hal drivers, utility files and libraries needed to build a Zephyr application running on Apollo silicon.
This module is updated regularly in order for Ambiq users to benefit from the latest AmbiqSuite versions, features and bug fixes. Updates are generally done once in each Zephyr release, preferably soon after the opening of the merge window to give time to users to use it, potentially report issues if some are faced and get them fixed before the new version in released.

With added proper shims adapting it to Zephyr's APIs, ambiq will provide peripheral drivers for Apollo SoCs.
ambiq hal is a standalone set of drivers for peripherals present in Ambiq Micro's SoCs. It originated as an extract from the AmbiqSuite SDK. The intention was to provide drivers that can be used in various environments without the necessity to integrate other parts of the SDK into them. This package also contains definitions of register structures and bitfields for all supported SoCs.
It may happen that you want to access Ambiq HAL APIs in your application, either because it is not available as a zephyr API or because you want to by-pass use of existing Zephyr API. In this case, you need to create a Kconfig file in your application which contains the following:
mainmenu "MYAPP"
source "Kconfig.zephyr"
config MYAPP_AMBIQ
default y
bool
select AMBIQ_HAL_USE_FOO
Additionally, you need to add the following includes:
#include <soc.h>
#include <am_mcu_apollo.h>CMSIS header files
