SPC5604BCLQ GPIO output control MIOS, program run error

22992113 · ‎10-17-2019

I have encountered some problems in the use of SPC5604BCLQ 144pin .

I want to control Enable/Disable 5V out for sensor.

I select PG2 to set GPIO Output to control it.

There will be some error occur when I Enable the SIU.GPDO[98].B.PDO = 1; as the picture below.

I redo a minimal system circuit, no other input and output pins connected, the program can run normally

Now I want to know if there is a problem with my hardware or software program, how can I solve the problem？

void IOInit(void)

{

   SIU.PCR[98].B.ODE = 1;
   SIU.PCR[98].B.OBE = 1;
   SIU.PCR[98].B.IBE = 0;
   SIU.GPDO[98].B.PDO = 1;

}

void main(void)

{

asm(" wrteei 0"); // DisableInterrupt;
disableWatchdog();

ME.RUNPC[0].R = 0x000000FE;

   /*****************************************
   enable PIT_RTI
   *****************************************/
   ME.PCTL[92].R = 0x00;

   / *****************************************
   enable SIUL
   *****************************************/
   ME.PCTL[68].R = 0x00;

SetupPll();

IOInit();

SIU.GPDO[98].B.PDO = 0; //5v output

for (;;)

{

......

}

Hi,

you are not initializing the Mode Entry module correctly, so the SIU module is still freezed and not accessible.

Please take a look at this SW example where you can find how to do that (function FMPLL_init):
