==Introduction==
This chapter contains the pinout description of the Naon module, grouped in four tables (two – odd and even pins – for each connector) that report the pin mapping of the two 140 pin Naon connectors.
Each row in the pinout tables contains the following information:
** Voltage: I/O voltage levels
The Internal connection column reports the name of the microprocessor signal, which in turn contains references to all the peripheral functions that can be associated to that pin. For example, the following pin name <code>CPU.VOUT[1]_B_CB_C[4]/EMAC[1]_MRXD[0]/VIN[1]A_D[1]/UART4_RXD/GP3[1]</code> means that the pin can be used as:
* <code>VOUT[1]_B_CB_C[4]</code>: Video output data, port 1, B/CB/C color bit 4
* <code>EMAC[1]_MRXD[0]</code>: Ethernet MAC, port 1, [G]MII Receive Data, bit 0
* <code>VIN[1]A_D[1]</code>: Video input channel 1, port A data input bit 1
* <code>UART[4]_RXD</code>: UART port 4, receive data input
* <code>GP3[1]</code>: General Purpose I/O port 3, channel 1
The following table reports all the function names that can be found on the Internal connection and the associated description.
