Interrupt Enable (IE): Global control all UART interrupts.

0 = interrupts disabled.

1 = interrupts enabled.

NOTE: This bit is not valid when in Loopback mode.

Request to Send (RTS):

Non-Autoflow mode: When not in Autoflow mode (AFE bit of MCR is clear), this bit

controls the Request-to-Send (RTS#) output pin.

0 = RTS# pin is 1

1 = RTS# pin is 0

Autoflow mode: When in Autoflow mode (AFE bit of MCR is set), auto-RTS is

enabled. RTS# behaves as follows:

• Auto-RTS disabled. Autoflow works only with auto-CTS.

• Auto-RTS enabled. Autoflow works with both auto-CTS and auto-RTS.
