PWM: A PWM (pulse width modulation) circuit is built-in SNC710. PWM can convert
input digital data into pulse trains with suitable different pulse width. The maximum
resolution of PWM is 10 bits. Two huge output stage circuits are included in SNC710.
Both of them are capable of driving speaker directly. The recommended application
circuit is as follows.
