Input Signal Definitions
The MC33816 EVB has nine logic level input signals used to control certain outputs or functions inside
the circuit. These 9 signals are:
1.
DRVEN
- Controls the state of the all the pre-driver outputs
2.
RESETB
- When the RESETB line is held low, the MC33816 is reset
3.
START1
- Provides start signal for Injector 1
4.
START2
- Provides start signal for Injector 2
