RLC is set automatically with entering Restart mode or Fail-safe mode. This guarantees a safe reset period in case of serious failure
situations. External reset spikes are lengthened by the SBC until the programmed reset length is reached.
If WEN is not set, the WAKE port is completely disabled. There is no change of the bits EWS and WLS within the System Status register.
