This bit enables Receive Error (RE) flags (NF, PF, FE, an OR) to create interrupt requests.
0
Error interrupt requests disabled
1
Error interrupt requests enabled
3
TE
Transmitter Enable
This bit enables the SCI transmitter, configuring the TXD pin as the SCI transmitter output.

0
SBK
Send Break
Toggling SBK sends one break character (10 or 11 Logic 0s). As long as SBK is set, the transmitter
sends Logic 0s.
