3.3.6 Ignition Control
DOUT1/2/3/4 can be used to control ignition key. They are Open-Drain type with no internal
pull-up resistor which also be used to control a relay. It means that the user has to connect a
pull-up resistor or a relay coil between the DOUT1/2/3/4 pin and any positive voltage to
generate a correct output. The DOUT1/2/3/4 pin can drive a continuous current of 0.2A.
The electrical conditions of it are:
