The macros defined here provide the HAL APIs for handling interrupts and the clock.

Usage: #include <cyg/hal/hal_intr.h>

Typedefs

typedef cyg_uint32 CYG_INTERRUPT_STATE
 Stores content of interrupt register (EXR).


Enumerations

enum  cyg_ISR_results { CYG_ISR_HANDLED = 1, CYG_ISR_CALL_DSR = 2 }

Functions

externC cyg_uint32 hal_default_isr (CYG_ADDRWORD vector, CYG_ADDRWORD data)
 Default interrupt service routine in common HAL code.

externC void hal_interrupt_stack_call_pending_DSRs (void)
 Execute pending DSRs on the interrupt stack with interrupts enabled.

externC void __default_interrupt_vsr (void)
 The default interrupt vsr defined in vectors.S.

externC void __default_exception_vsr (void)
 The default exception vsr defined in vectors.S.


Variables

externC volatile CYG_ADDRESS hal_interrupt_handlers [CYGNUM_HAL_ISR_COUNT]
 Table stores interrupt handlers for each vector (vectors.S).

externC volatile CYG_ADDRWORD hal_interrupt_data [CYGNUM_HAL_ISR_COUNT]
 Table stores interrupt data to be passed to ISR when executed (vectors.S).

externC volatile CYG_ADDRESS hal_interrupt_objects [CYGNUM_HAL_ISR_COUNT]
 Table stores interrupt object pointers - required by kernel (vectors.S).

externC volatile CYG_ADDRESS hal_vsr_table [CYGNUM_HAL_VSR_COUNT]
 This table contains the vector service routines for all vectors (vectors.S).

Function Documentation

externC void __default_exception_vsr (  void   ) 
 

The default exception vsr defined in vectors.S.

externC void __default_interrupt_vsr (  void   ) 
 

The default interrupt vsr defined in vectors.S.

externC cyg_uint32 hal_default_isr (  CYG_ADDRWORD  vector,
