4.1 Init Controller Descriptor

The PL360 Host Controller is initialized by calling the atpl360_init function in the API. The PL360 Host Controller initialization routine performs the following actions:

• Disable PLC interrupt and component
• Register wrapper for Hardware Abstraction Layer (for further information, please refer to Initialization Function)
• Reset the PL360 device using corresponding host MCU control GPIOs
• Configure a GPIO as an interrupt source from the PL360 device
• Initialize the SPI driver
• Register an internal event handler for the external PLC interrupt
• If an add-on is required, initialize specific add-on (configured previously). See chapter Configure Application
• Return a descriptor to the PL360 Host Controller. This descriptor will be used to manage the PLC communication
