5.2.10. Internal Loopback
The internal loopback capability of the UARTs is enabled by setting Modem Control Register bit-4
(MCR[4]) to 1. When the feature is enabled, the data from the output of the transmit shift register are
looped back to the input of the receive shift register. This feature provides the users a way to perform
system diagnostics by allowing the UART to receive the same data it is sending.
