about SWT

Question asked by 从涛 徐 on May 15, 2018

Hi,

  Now,I have some questoins to ask about SWT(soft watching dog).

  The first is how can triggle the SWT to cause a reset request.And if need to write a interrupthandler to reset.Or the reset request is sent to FCCU and reset automatic.

 

 The second question is about S32R274 SWT example.

In the void FCCU_Init()

#if LONG_RESET
  /* Configure FCCU to react on NCF14 with long functional reset */
  FCCU.NCFS_CFG[0].R = 0x20000000;    //long functional reset reaction

#else
  /* Configure FCCU to react on NCF with short reset */
  FCCU.NCFS_CFG[0].R = 0x10000000;

#endif

In the datasheet:

01 Short functional reset request pulse (FAULT state reaction)
10 Long functional reset request pulse (FAULT state reaction)

according to the datasheet ,why the FCCU.NCFS_CFG[0].R = 0x20000000 and FCCU.NCFS_CFG[0].R = 0x10000000?Not is FCCU.NCFS_CFG[0].R = 0x80000000,and FCCU.NCFS_CFG[0].R = 0x40000000.

That all.Thanks.
