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 new functionality, as shown in
Table 17.
The driver configuration is selected with two programmable registers PWMINT1 = 0x93 and
PWMINT2 = 0x81 (see
