The SBC can not be sent from Normal Mode to Sleep Mode with uncleared interrupt in the WK interrupt bits “WK
0 WK pin” and “WK 1 WK pin”. This is implemented to avoid that a wake information from the WK pin gets lost
during the transition from Normal to Sleep Mode. If a wake up appears during the µC sets the SBC to Sleep Mode,
the SBC will wake up directly after going to Sleep Mode. There is no difference if the bits “WK 0 WK pin” or “WK
1 WK pin” bit were set during the transition or were just not cleared before sending the SPI command for Sleep
Mode, the SBC will wake-up after entering the Sleep Mode. Therefore it always needs to be ensured that the bits
are cleared before sending the SBC to Sleep Mode.
