Changes from V1.00:
|
||||
|
||||
+ Call to taskYIELD() from within tick ISR has been replaced by the more
|
||||
efficient portSWITCH_CONTEXT().
|
||||
+ ISR function definitions renamed to include the prv prefix.
|
||||
|
||||
Changes from V1.2.0:
|
||||
|
||||
+ portRESET_PIC() is now called last thing before the end of the preemptive
|
||||
tick routine.
|
||||
|
||||
Changes from V2.6.1
|
||||
|
||||
+ Replaced the sUsingPreemption variable with the configUSE_PREEMPTION
|
||||
macro to be consistent with the later ports.
