Xmega Application Note | |||||
This file contains the function implementations for the XMEGA Programmable Multi-level Interrupt Controller driver/example.
The driver is not intended for size and/or speed critical code, since most functions are just a few lines of code, and the function call overhead would decrease code performance. The driver is intended for rapid prototyping and documentation purposes for getting started with the XMEGA PMIC module.
For size and/or speed critical code, it is recommended to copy the function contents directly into your application instead of making a function call.

Functions | |
void | PMIC_SetVectorLocationToApplication (void) |
Move interrupt vector table to application area. | |
void | PMIC_SetVectorLocationToBoot (void) |
Move interrupt vector table to boot area. |
void PMIC_SetVectorLocationToApplication | ( | void | ) |
Move interrupt vector table to application area.
This function moves the interrupt vector table to application area. The function writes the correct signature to the Configuration Change Protection register before writing the CTRL register. Interrupts are automatically ignored during the change enable period.
