This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SCI interrupt is generated whenever OR = 1 or RDRF = 1 in the SCISR
register.
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SCI interrupt is generated whenever IDLE = 1 in the SCISR register.
This bit enables the transmitter. It is set and cleared by software.
0: Transmitter is disabled
1: Transmitter is enabled
Notes:
- During transmission, a ‘0’ pulse on the TE bit (‘0’ followed by ‘1’) sends a preamble
(Idle line) after the current word.
- When TE is set there is a 1 bit-time delay before the transmission starts.
Caution: The TDO pin is free for general purpose I/O only when the TE and RE bits
are both cleared (or if TE is never set).
This bit enables the receiver. It is set and cleared by software.
0: Receiver is disabled
1: Receiver is enabled and begins searching for a start bit
Note: Before selecting Mute mode (setting the RWU bit), the SCI must first receive
some data, otherwise it cannot function in Mute mode with Wake-Up by Idle line
detection.
This bit determines if the SCI is in mute mode or not. It is set and cleared by
software and can be cleared by hardware when a wake-up sequence is recognized.
0: Receiver in Active mode
1: Receiver in Mute mode
This bit set is used to send break characters. It is set and cleared by software.
0: No break character is transmitted.
1: Break characters are transmitted.
Note: If the SBK bit is set to ‘1’ and then to ‘0’, the transmitter will send a Break word
at the end of the current word.
