2.2.2 UART Connectivity (X3, X5, X6, X7)
The AM335x SOM supports up to 6 so called UART units. The phyBOARD-Regor provides the
interfaces of UART0 to UART3 on various connectors at different signal levels.
Table 7
gives
an overview of the UART signals' availability, locations and signal levels.
For a more detailed description of each serial interface, refer to the appropriate chapter
listed in the table.
