intce.h

#include <intce.h>

This header includes defines and prototypes for working with user interrupts.

Warning

As of hardware revision I, user interrupt vectors are no longer supported. Some functions will no longer work on the newer hardware, and are labeled as such. Feel free to send TI a strongly worded email about this limitation.

API Documentation

Interrupt configuring and setting.

This file provides routines for setting custom interrupt vectors for your program. Note that TI broke interrupt support in hardware revisions >= I, and they will not work. Use at your own risk.

Warning

TI broke interrupt support on CE models with hardware revision >= I.

void int_Reset(void)

Warning

Must have called int_Initialize before using.

Warning

void int_SetVector(uint8_t ivect, void (*handler)(void))

Sets up an interrupt vector given an ISR.

Warning

TI broke interrupt support on CE models with hardware revision >= I.

Parameters

• handler – [in] Handler to interrupt service routine.
