how can go to halt mode from run and comeback to run? hoe can wakeup with lin?
hi friend
I am trying to set my borad into halt mode and then wake it up and set it to run mode.
I read AN3316 and write this code but its not work.
if(pal_lld_readpad(PORT_E, pushbutton)==0)
{
StopmodeFlag = 1U;
pal_lld_togglepad(PORT_H,LEDTEST);
osalThreadDelayMilliseconds(100);
pal_lld_togglepad(PORT_H,LEDTEST);
}
if (StopmodeFlag == 1U){
/*( Mode set in HALT) dar safhe 25 Application noteSPC560B power and mode management*/
ME.HALT0.B.CFLAON=2; //(code Flash in Low Power mode)
ME.HALT0.B.DFLAON=2; //(data Flash in Low Power mode)
ME.HALT0.B.FXOSC0ON = 1; //(turn-on the XTAL)
ME.HALT0.B.FMPLLON = 1; //(turn-on the PLL)
ME.HALT0.B.SYSCLK = 4; //(set PLL as device system clock)
/*(Peripheral mode set HALT mode:)*/
ME.LPPC[0].B.HALT0 = 1; //(activate low power peripheral configuration ’0’ in HALT)
ME.PCTL[4].B.LP_CFG = 0; // to select the low power peripheral configuration ’0’ for DSPI0 identified by offset = 4 (refer to figure x)
ME.PCTL[32].B.LP_CFG = 0; //to select the low power peripheral configuration ’0’ for ADC identified by offset = 32 (refer to figure x)
ME.PCTL[48].B.LP_CFG = 0; //to select the low power peripheral configuration ’0’ for lin identified by offset = 48 (refer to figure x)
ME.PCTL[16].B.LP_CFG = 0; //to select the low power peripheral configuration ’0’ for FlexCAN0 identified by offset = 16 (refer to figure x)
/*Timer set:See Step 5 (RUN0 to HALT mode)*/
/*Request transition to RUN0 mode: So, in case of RUN0 to HALT transition, these two register writing should be done:*/
ME.MCTL.R = 0x80005AF0;
ME.MCTL.R = 0x8000A50F;
while (ME.GS.B.S_MTRANS != 0){}
while (ME.IS.B.I_MTC != 0){}
}
void ConfigureWKPU(void) {
/* Enable WKPU PCTL */
SPCSetPeripheralClockMode(69,
SPC5_ME_PCTL_RUN(2) | SPC5_ME_PCTL_LP(3));
INTC_PSR(46) = 7;
WKUP.WRER.R = (1U << 0); // enable wakeup pin of:\n
WKUP.WIREER.R = (1U << 0); // enable rising edge interrupt for
WKUP.WISR.R = 0xFFFFFFFFU; // clear interrupt flags that an external interrupt occours
