1.1 Platform Abstraction Layer (PAL)
The Platform Abstraction Layer (PAL) contains the wrapper functions which provide the seamless interface between the MAC/PHY software to PAL modules.
The PAL provides interface for the following components:
- SYS timer services for software timers and delay routines
- Access to persistent storage (for example, Flash, NVM or EEPROM)
- NVIC module for enabling/disabling the Radio Frequency (RF) and arbiter interrupts
