CIF Peripheral Model - SimpleTimer

CoMET Version 5.9 – Tutorial 107

IP->BusClock = AmpiClockInitSlavePortView("BusClock", "All");

IP->Bus = AmpiStdBusInitSlavePortView("Bus", "All");

IP->Reset = AmpiLogicInitSlavePortView("Reset", "All");

Add the following after the IP->Reset line:

CODE BEGINS

IP->TimerClock = AmpiClockInitSlavePortView("TimerClock", "All");

CODE ENDS

Setup callback data structures

In the SimpleTimer.h instance structure we defined CallbackData, an array of

tTimerCallbackData structures, one for each match register. Here we initialize each structure.

After the slave port views input handles section, add the following:

CODE BEGINS

** Set up callback data structures

IP->CallbackData[MATCH1_IX].IP = IP;

IP->CallbackData[MATCH1_IX].regMTRN = MATCH1_IX;

IP->CallbackData[MATCH2_IX].IP = IP;

IP->CallbackData[MATCH2_IX].regMTRN = MATCH2_IX;

CODE ENDS

In the SimpleTimer.h instance structure we defined callback handle arrays, MatchEvent and

UnmatchEvent. Here we register the callback functions with the scheduler and store the

returned callback handles in the callback handle arrays.

The callback functions section looks similar to the following:

**Register Callback functions if required for any other inputs

In the callback functions section, add the following

CODE BEGINS

IP->MatchEvent[MATCH1_IX] = AmpiTaskRegisterCallback(Match,

(void *)&IP->CallbackData[MATCH1_IX], IP->TimerClock);

IP->MatchEvent[MATCH2_IX] = AmpiTaskRegisterCallback(Match,

(void *)&IP->CallbackData[MATCH2_IX], IP->TimerClock);

IP->UnmatchEvent[MATCH1_IX] = AmpiTaskRegisterCallback(Unmatch,

(void *)&IP->CallbackData[MATCH1_IX], IP->TimerClock);

IP->UnmatchEvent[MATCH2_IX] = AmpiTaskRegisterCallback(Unmatch,

(void *)&IP->CallbackData[MATCH2_IX], IP->TimerClock);

CODE ENDS
