initialize_Interrupt

Definition

Error initialize_Interrupt(Interrupt_Config config);

Description:
This function initializes an interrupt with the supplied configuration. Resistor configuration and tristate variables are contained within this function and do not need to be implemented externally.

Parameters:

• Interrupt_Config config: this parameter is a completely filled out Interrupt_Config structure. All parameters should be initialized to some known value to ensure desired interrupt functionality is achieved.

Return

This function will return an error code associated with its success:

• ERR_INVALID_ENUM: This will be returned if the enumeration was not a valid enumeration for an external interrupt.
• ERR_INVALID_PIN: This will be returned if the specified pin is not available for the specified interrupt.

enable_Interrupt

Definition

void enable_Interrupt(Interrupt extInt);

Description: This function simply enables the interrupt specified in the interrupt parameter.

Parameters:

• Interrupt extInt: this parameter specifies which Interrupt should be enabled.
