31.3.2.3 eSCI Control Register 2 (eSCI_CR2)
This register provides bits to configure the functionality of the module, and interrupt enable bits for the
interrupt flags provided in eSCI Interrupt Flag and Status Register 1 (eSCI_IFSR1) and control bits for the
transmitter and receiver.
RWU Receiver Wake-Up Mode. This bit controls and indicates the receiver wake-up mode, which is described in
Section 31.4.5.5, Multiprocessor Communication.
0 Normal receiver operation.
1 Receiver is in wake-up mode.
Note: This bit should be set in SCI mode only.
SBK Send Break Character. This bit controls the transmission of break characters, which is described in
Section 31.4.5.2.7, Break Character Transmission.
0 No break characters are transmitted.
1 Break characters are transmitted.
Note: This bit should be set in SCI mode only.
