17.2.3
17.3
This section lists the name and description of all external ports.
17.3.1
This analog pin drives the unbuffered analog output voltage from the DAC resistor network output, if the
according mode is selected.
17.3.2
This analog pin is used for the buffered analog output voltage from the operational amplifier output, if the
according mode is selected.
17.3.3
This analog input pin is used as input signal for the operational amplifier positive input pin, if the according
mode is selected.
Freescale Semiconductor
If the “Unbuffered DAC” mode was used before entering stop mode, then the DACU pin will reach
VRH voltage level during stop mode.
The content of the configuration registers is unchanged.
