Device Header File <device.h>

The Device Header File <device.h> contains the following sections that are device specific:

- Interrupt Number Definition provides interrupt numbers (IRQn) for all exceptions and interrupts of the device.
- Configuration of the Processor and Core Peripherals reflect the features of the device.
- Device Peripheral Access Layer provides definitions for the Peripheral Access to all device peripherals. It contains all data structures and the address mapping for device-specific peripherals.
- Access Functions for Peripherals (optional) provide additional helper functions for peripherals that are useful for programming of these peripherals. Access Functions may be provided as inline functions or can be extern references to a device-specific library provided by the silicon vendor.

Reference describes the standard features and functions of the Device Header File <device.h> in detail.

# Interrupt Number Definition

Device Header File <device.h> contains the enumeration IRQn_Type that defines all exceptions and interrupts of the device.

- Negative IRQn values represent processor core exceptions (internal interrupts).
- Positive IRQn values represent device-specific exceptions (external interrupts). The first device-specific interrupt has the IRQn value 0. The IRQn values needs extension to reflect the device-specific interrupt vector table in the Startup File startup_<device>.s (deprecated).

Example:

The following example shows the extension of the interrupt vector table for the LPC1100 device family.

typedef enum IRQn
{
/****** Cortex-M0 Processor Exceptions Numbers ***************************************************/
NonMaskableInt_IRQn = -14,
HardFault_IRQn = -13,
SVCall_IRQn = -5,
PendSV_IRQn = -2,
SysTick_IRQn = -1,
/****** LPC11xx/LPC11Cxx Specific Interrupt Numbers **********************************************/
WAKEUP0_IRQn = 0,
WAKEUP1_IRQn = 1,
WAKEUP2_IRQn = 2,

EINT1_IRQn = 30,
EINT0_IRQn = 31,
} IRQn_Type;

# Configuration of the Processor and Core Peripherals

The Device Header File <device.h> configures the Cortex-M or SecurCore processor and the core peripherals with #defines that are set prior to including the file core_<cpu>.h.

The following tables list the #defines along with the possible values for each processor core. If these #defines are missing default values are used. core_cm0.h

# Device Peripheral Access Layer

The Device Header File <device.h> contains for each peripheral:

- Register Layout Typedef
- Base Address
- Access Definitions

The section Peripheral Access shows examples for peripheral definitions.

# Device.h Template File

The silicon vendor needs to extend the Device.h template file with the CMSIS features described above. In addition the Device Header File <device.h> may contain functions to access device-specific peripherals. The system_Device.h Template File which is provided as part of the CMSIS specification is shown below.
