ADC Chip Select Line
ADC (U20) control lines enabled.
ADC (U20) control lines disabled. This authorizes users to connect the
corresponding chip select line to their own resources via the I/O expansion
connector.
Standard Power Supply Supervisory Enabling
Standard power supply is supervised by the ADC (U20) channel 1 via a
resistor bridge. The ratio is set to 0.1013 so that the standard power supply
can be supervised up to 15V.
Standard power supply is not connected to the ADC (U20) channel 1. This
allows the user to connect the corresponding ADC channel to their own
resources via the I/O expansion connector.
VDDCORE Voltage Monitoring
The ADC channel 3 is connected at the V
the user to tune the frequency clock according to the core voltage.
The ADC channel 3 is not connected and it is available on the I/O expansion
connector for user application.
Battery Power Supply Supervisory Enabling
Battery power supply is supervised by the ADC (U20) channel 2 via a
resistor bridge. The ratio is set to 0.24 so that the battery voltage range can
be supervised (5.5V to 6.2V).
Battery power supply is not connected to the ADC (U20) channel 2. This
authorizes the user to connect the corresponding ADC channel to their own
resources via the I/O expansion connector.
Ambient Temperature Monitoring
The ADC channel 0 is connected to a temperature sensor near the
32.768 kHz crystal. This allows the user to evaluate the frequency drift
according to the ambient temperature.
The ADC channel 0 is not connected and it is available on the I/O expansion
connector for the user application.
