As to switch from INIT_FS mode to Normal_WD mode in SBC, 1 good watchdog refresh is essential by MCU; but if the MCU fails to do so in 256msec, then RSTB, FS0B & FS1B(after Tdelay time) are asserted low. So at this time, SBC remains in INIT_FS mode only & the window of 256msec expires, then what happens next? Does it move into Deep Failsafe state? or SBC restarts?
Thanks in advance.
