3.12 Pin Configuration Input / Output
VNC2 has multiple interfaces available for connecting to external devices. These are UART, FIFO, SPI
slave, SPI master, GPIO and PWM. The Interface I/O Multiplexer is used to share the available I/O Pins
between each peripheral.
VNC2 is configured with default settings for the I/O pins however they can be easily changed to suit the
needs of a designer. This is explained in Section 5 – I/O Multiplexer. Default configuration for each
package type is shown in Table 6- Default I/O Configuration. The signal names are also indicated for
the VNC1L device as it is pin-compatible with the 48 pin LQFP VNC2 device.
Note: The default value of the pins listed in the following table are only available when the I/O
Mux is enabled. A blank VNC2 chip default is all pins are inputs.
