Pin description

OUT1A, 1B, 2A and 2B (pins 16, 10, 9 and 3)

Output half bridge PWM outputs 1A, 1B, 2A and 2B provide the input signals to the

speakers.

RESET (pin 22)

Driving RESET low sets all outputs low and returns all register settings to their default

(reset) values. The reset is asynchronous to the internal clock.
