The pins of Port Number #3 will be connected (and usable as CAN Bus at TTL level or as two General Purpose IOs) only in case that the board is not configured
with dedicated CAN transceiver, accessible through connector CN24. Please check also par. 3.3.10.
Moreover, As a factory option, it is possible to have UART4 (port #4) configured with TTL or RS-232 interface, UART1 (ports #8) with TTL or RS-485 interface and
UART5 with TTL level or RS-232 interface (Tx and Rx signals only). All possible factory configurations are described in the table below.
Please consider that the pins dedicated to UART1, UART4 and UART5 can be used as General Purpose I/Os exclusively in the case that the corresponding UART
is at TTL level (which means with no RS-232 or RS-485 transceiver interposed). This is the situation of the first configuration described in the following table.
Port number# Configuration #1
Port #4 UART4 TTL level Full
Port #8 UART1 (Tx,Rx) TTL
Port #9 UART5 TTL level Full
Configuration #5 is the standard offered with SBC-A62-J modules with i.MX6S (Solo) and i.MX6DL (Dual Lite) processor.
Configuration #4 is the standard offered with SBC-A62-J modules with i.MX6DP (Dual Plus) and i.MX6Q (Quad) processor.
