Temperature Sensor Enabling
The temperature sensor device is connected to the ADC channel 1 (AD1)
input.
The temperature sensor device is not connected to the ADC channel 1 (AD1)
input. This authorizes users to connect the corresponding ADC channel to their
own resources via the I/O expansion connector.
Analog Converter Peripherals Loopback
DAC Channel 0 is connected to ADC Channel 4 for test purposes.
DAC Channel 0 is not connected to ADC Channel 4. This authorizes users to
connect the corresponding Analog Channels to their own resources via the I/O
expansion connector.
Analog Converters Peripherals Loopback
DAC Channel 1 is connected to ADC Channel 0 for test purposes.
DAC Channel 1 is not connected to ADC Channel 0. This authorizes users to
connect the corresponding Analog Channels to their own resources via the I/O
expansion connector.
On-board Boot Chip Select
NCS0 select signal is connected to the Flash memory.
NCS0 select signal is not connected to the Flash memory. This authorizes
users to connect the corresponding select signal to their own resources via the
EBI expansion connector.
Flash Reset
The on-board reset signal is connected to the Flash RESET input.
The on-board reset signal is not connected to the Flash RESET input.
Boot Mode Strap Configuration
The BMS MCU input pin is set for the microcontroller to boot on an external
16-bit memory at reset.
The BMS MCU input pin is set for the microcontroller to boot on an external
8-bit memory at reset.
