1.
Limitations on A4 and A5, related to I
2
C configuration, are explained in Table 9. Solder bridge configuration according to
SB2/SB3 setting.
2.
Only one USART is available and shared between ARDUINO
®
Nano and VCP. The selection is done by remapping (no
need to change the hardware configuration).
3. D7/D8 are shared with OSC_IN/OSC_OUT.
4. SPI_CS is handled by GPIO.
