How we can enable the MCU_CLKOUT on N8 pin for iwr6843.
below are the steps I have followed but it is not enabled.
Pinmux_Set_OverrideCtrl(SOC_XWR68XX_PINN8_PADAY,PINMUX_OUTEN_RETAIN_HW_CTRL,PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR68XX_PINN8_PADAY,SOC_XWR68XX_PINN8_PADAY_MCU_CLKOUT);
static void PMIC_SignalGenerator_MCU_CLKOUT_Handling(void)
{
SOC_Handle socHandle;
SOC_Cfg socCfg;
int32_t errCode;
SOC_DriverMCB* ptrSOCDriverMCB;
/* Initialize the SOC Module: This is done as soon as the application is started
* to ensure that the MPU is correctly configured. */
socHandle = SOC_init (&socCfg, &errCode);
if (socHandle == NULL)
{
//System_printf ("Error: SOC Module Initialization failed [Error code %d]\n", errCode);
MmwDemo_debugAssert (0);
}
/* Get the pointer to the SOC Driver Block: */
ptrSOCDriverMCB = (SOC_DriverMCB*)socHandle;
//ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKCTL = 0xD;
/* Disable the clock by gating off the clock */
ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKCTL = CSL_FINSR (ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKCTL, 7U, 0U, 0U);
ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKDIV = CSL_FINSR (ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKDIV,7U,0U, 1U);
//ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKDIV = 1U;
ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKSRCSEL = CSL_FINSR (ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKSRCSEL,3U,0U, 4U);
//ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKSRCSEL = 4U;
//ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKCTL = 0U;
ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKCTL = CSL_FINSR (ptrSOCDriverMCB->ptrTopRCMRegs->EXTCLKCTL, 7U, 0U, 0xAD);
}
when I checked result with help of CRO, that MCU_CLKOUT pin is not toggling.
is there any extra register need to configure the MCU_CLKOUT functionality.
if knows please reply back.
