Chapter 18. Device Driver Interface to the Kernel
Result:
None
Description:
Deferred Service Routine prototype. A pointer to a function with this prototype is passed to
cyg_interrupt_create()
when an interrupt object is created. When the ISR requests the scheduling of its
DSR, this function will be called at some later point. In addition to the
vector
and
data
arguments, which
will be the same as those passed to the ISR, this routine is also passed a
count
of the number of times the
ISR has requested that this DSR be scheduled. This counter is zeroed each time the DSR actually runs, so it
indicates how many interrupts have occurred since it last ran.
