For measurement reasons the voltages are scaled to low
voltage domain V33I. The scaled voltages are converted
by the on chip ADC. For scaling factor look at chapter
Electrical Functions section
conversion results can be read by access to the result
registers. The VBUSP is an average value (t
ADC control cycle consists of two conversion cycles. The
bus voltage is converted in the first conversion cycle of
every control cycle. All other analog channels are con-

verted in the second slot of the control cycle. The result-
ing conversion rate is approximately
• 70 k samples for bus voltage
• 10 .. 20 k samples for all other sources
Note: From VST supervision an active SAVE_N signal is gener-
ated in case of falling supply voltages. This allows the host pro-
cessor to stop the application program and to save its data be-
fore the reset pin RESET_N becomes active.
