Comtrol eCos - Manual (Page 407)

Chapter 18. Device Driver Interface to the Kernel
Arguments:
vector - vector to unmask
Result:
None
Level:
ISR
Description:
Program the interrupt controller to re-allow delivery of interrupts on the given vector . This version differs
from cyg_drv_interrupt_unmask() in not being interrupt safe.
cyg_drv_interrupt_acknowledge
Function:
void cyg_drv_interrupt_acknowledge( cyg_vector_t vector )
Arguments:
vector - vector to acknowledge
Result:
None
Level:
ISR
Description:
Perform any processing required at the interrupt controller and in the CPU to cancel the current interrupt
request on the
vector . An ISR may also need to program the hardware of the device to prevent an immediate
re-triggering of the interrupt.
cyg_drv_interrupt_configure
Function:
void cyg_drv_interrupt_configure( cyg_vector_t vector,
cyg_bool_t level,
cyg_bool_t up
)
Arguments:
vector - vector to configure
