Driver configuration

STA529

Doc ID 13095 Rev 3

Driver configuration

A driver configuration is available that allows PWM commands to be used on an external

power device. For this purpose, the output serial audio interface is disabled and the

respective pins have an alternative name and a new function, as shown in Table 19.

The driver configuration is selected with the two programmable registers, PWMINT1 = 0x93

and PWMINT2 = 0x81, on page 51.

8.1

I2S bypass

A configuration is available which allows the passing of the I2S input signal straight to the

I2S output signal.

This configuration is set using two programmable registers PWMINT1 = 0x93 and

PWMINT2 = 0x80.
