The PWM can be programmed to select one of two clock signals as its source frequency, xtal clock or
hsadc clock. The selected clock signal is passed through a prescaler before being input to the counter. The
output is available at the pulse width modulator output (PWMO) external pin.
PWM also supports MATT mode. In this mode, it can be programmed to select one of two clock signals
as its source frequency, 24-MHz or 32-KHz crystal clock. For a 32-KHz source clock input, the PWM
outputs the 32-KHz clock directly to PAD.
