Table 1 Logic table; note 1
Notes
1. X = don’t care.
2. BD, SU and DD logic levels are with respect to SGND;
3. GHL logic levels are with respect to SHL;
4. If pin DD = LOW the bridge enters the state (oscillation state and pin BD = LOW and pin SU = HIGH) in the
5. Only if the level of pin EXTDR changes from HIGH-to-LOW, the level of outputs GHL, GHR, GLL and GLR changes

EXTDR logic levels are with respect to LVS.
GHR logic levels are with respect to SHR;
GLL and GLR logic levels are with respect to PGND.
pre-defined position pin GHL = HIGH, pin GLR = HIGH, pin GLL = LOW and pin GHR = LOW.
