-  Two UART ports are available:
+  Virtual COM / DBGU Port.  Either may be driven by USART3, depending
+  upon the setting of JP2 (DBGU_PE):
 
-  Virtual COM / DBGU Port (J24).  Either may be driven by USART3, depending
-  upon the setting of JP19 and JP20:

+  Terminologicy: FLEXCOM is the same as USART in previous SAMA5D versions.
 
-  In one jumper position UART3 connects to the SAM3U which will, in turn,
-  provide the serial output over a USB virtual COM port.  In other other
-  jumper position, UART3 will connect the RS-232 port labelled DBGU (J24).
+  Standard UART on Arduino connector (J21) is FLEXCOM4.
 
-  I personally prefer the RS-232 port because my terminal software does not
-  lose the USB Virtual COM every time I reset or power-cycle the board.

-  A TTL-to-RS232 converter is required to use this USART for a serial console.

-  - RXD4/PE26 is available at Expansion Interface, J19C pin 59
-  - TXD4/PE27 is available at Expansion Interface, J19C pin 60
-  - VCC_3V3 is also available at Expansion Interface, J19B pins 21 and 22
-  - GND is available J19A pin 11, J19B pin 31, and J19C pin 51
+  UARTs available of EXT1
 
-  By default the RS-232 DBGU port on USART3 is used as the NuttX serial
-  console in all configurations (unless otherwise noted).  USART4, however,
-  is the also available.
