(#) FIFO mode enabling/disabling and RX/TX FIFO threshold programming.

|
|
|
-@- When USART operates in FIFO mode, FIFO mode must be enabled prior
|
|
starting RX/TX transfers. Also RX/TX FIFO thresholds must be
|
|
configured prior starting RX/TX transfers.
|
|
|
|
(#) Slave mode enabling/disabling and NSS pin configuration.
|
|
|
|
-@- When USART operates in Slave mode, Slave mode must be enabled prior
|
|
starting RX/TX transfers.
