Hardware API Layers - SC12 @CHIP-RTOS V1.10

Hardware API Layers

Layer model:

1. INT 6Fh     - Service Interrupt Handler
   
   The service interrupt provides software compatibility with the Beck FEC product line.   This interrupt is used only in Beck products based on the IPC@CHIP and is not part of the standard @CHIP-RTOS.   These services use the PFE and HAL interfaces to contact the actual hardware.
   
   
2. PFE     - Pin Function Enabler
   
   This part of the hardware API provides functions to control the IPC@CHIP's multi-function I/O pins.
   
   

3. HAL     - Hardware Abstraction Layer
   
   This part of the hardware API provide an isolation layer between your application software and the IPC@CHIP hardware (PIO pins, timers, etc.) which minimizes hardware dependencies.
