A) Tristate when affected by undervoltage shut down or short circuit
B) 0 when affected; 1 when not affected; self recovery
C) 0V when output does not correspond to input patterns; 5V when output corresponds to
input patterns
D) Is an output affected by undervoltage ER2 is 0V
E) 0 when affected– the outputs of the affected halfbridge are shut down and stay latched
until reset; 1 when not affected
F) 0V when output does not correspond to input patterns – the outputs of the affected half-
bridge are shut down and stay latched until reset; 5V when output corresponds to input
patterns.
T) Tristate
X) Condition has no influence
Remark: To generate fast decay control mode, set PWM to 1 and send pwm-pattern to DIR
input.
