Legacy HAL	The Legacy HAL is an implementation of the Hardware Abstraction Layer (HAL) that was used by the Zigbee EmberZNet and Flex Connect stacks before their transition to the new component-based architecture (Zigbee version 7.0 and Connect version 3.0). This component is not a complete duplicate of the old HAL. It only contains the most commonly used pieces to enable our networking stacks and sample applications and to support porting customer applications to the new component-based implementation. Currently, Zigbee and Connect sample applications are dependent on this component. Eventually, they will be ported to use new HAL components directly so that this component can become optional or be deprecated Application Bootloader Interface - Definition of the application bootloader interface Button - Sample API functions for using push-buttons Common Bootloader - Common bootloader interface defines and functions Cyclic Redundancy Check - Functions that provide access to cyclic redundancy code (CRC) calculation. See crc.h for source code Diagnostics - Crash and watchdog diagnostic functions LED - Sample API funtions for controlling LEDs Microcontroller functions - Microcontroller functions Random generation - Functions that provide access to random numbers Reset Cause Definitions - Definitions for all the reset cause types Standalone Bootloader - Definition of the standalone bootloader interface Library initialization Message authentication codes Message digests

RAM execution disable	RAM execution disable utilities can be used to disable execution from RAM and other selected memory regions
Interrupt Manager	Platform level software module that manages the system's Interrupts
RAM interrupt vector initialization	Simple utility to move the interrupt vector table to RAM
Sleep Timer	Sleep Timer can be used for creating timers
