S12ZVMC128   Overcurrent  protection

I use S12ZVMC128  and  I have some problems with the overcurrent protection. And I think it maybe the bug of this MCU.

I use the Current Amplifier 0  and Comparator 0 , and I set '0'  to the GOCA0  . when overcurrent condition come out , the highside MOS will turn off , and the lowside MOS will turn on .

the problem is that there is no deadtime insertion (4us) between  MOSFET swichs . and in normal condition ,there is deadtime insertion .

what can I do to resolve this problem ?
