Function Documentation

void SIM_GetUniqueId

(

sim_uid_t *

uid

)

Parameters

uid	Pointer to the structure to save the UID value.

static uint32_t SIM_GetSysResetStatus ( void  )

inlinestatic

This function gets the SIM reset source. Use source masks defined in the sim_reset_source_t to get the desired source status.

This is an example.

   uint32_t resetStatus;

// To get all reset source statuses.
   resetStatus = SIM_GetSysResetStatus() & kSIM_SourceAll;

   // To test whether the MCU is reset using Watchdog.
   resetStatus = SIM_GetSysResetStatus() & kSIM_SourceWdog;

   // To test multiple reset sources.
   resetStatus = SIM_GetSysResetStatus() & (kSIM_SourceWdog | kSIM_SourcePin);

Returns

system reset status.
