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.
