18.9.3 SCI Control Register 3
MC68HC908GP32
MOTOROLA
NOTE:
•
MC68HC08GP32
Address:
SBK — Send Break Bit
Do not toggle the SBK bit immediately after setting the SCTE bit.
Toggling SBK before the preamble begins causes the SCI to send a
break character instead of a preamble.
SCI control register 3:
Reset:
Read:
Write:
Setting and then clearing this read/write bit transmits a break
character followed by a logic 1. The logic 1 after the break character
guarantees recognition of a valid start bit. If SBK remains set, the
transmitter continuously transmits break characters with no logic 1s
between them. Reset clears the SBK bit.

Serial Communications Interface Module (SCI)
1 = Transmit break characters
0 = No break characters being transmitted
Stores the ninth SCI data bit received and the ninth SCI data bit to
be transmitted
Enables these interrupts:
– Receiver overrun interrupts
– Noise error interrupts
– Framing error interrupts
Parity error interrupts
