2.42 External Interrupt Controller (EIC)
This Plib implements software abstraction for EIC Peripheral.
Library Interface
External Interrupt Controller peripheral library provides the following interfaces:
Functions
| Name | Description |
|---|---|
| EIC_Initialize | Initializes given instance of EIC peripheral |
| EIC_InterruptEnable | Enable external interrupt on the specified pin |
| EIC_InterruptDisable | Disable external interrupt on the specified pin |
| EIC_CallbackRegister | Registers the function to be called when an interrupt condition has been sensed on the pin |
| EIC_SetPolarity | Sets the polarity of detection |
| EIC_FreezeConfiguration | Freeze EIC configuration |
| EIC_NMICallbackRegister | Registers the function to be called when an interrupt condition has been sensed on the NMI pin |
Data types and constants
| Name | Type | Description |
|---|---|---|
| EIC_PIN | Enum | Identifies the available EIC pins |
| EIC_POLARITY | Enum | Identifies all possible EIC polarities |
| EIC_CALLBACK | Typedef | Defines the data type and function signature of the EIC peripheral callback function |
| EIC_NMI_CALLBACK | Typedef | Defines the data type and function signature of the EIC peripheral NMI callback function |
Note: Not all APIs maybe implemented. See the specific device family
section for available APIs.
