Serial Communications Interface (SCI)
17.9.3 SCI Control Register 3
Technical Data
248
NOTE:
Address:
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:
R8 — Received Bit 8
Reset:
Read:
Write:
transmitter continuously transmits break characters with no logic 1s
between them. Reset clears the SBK bit.
•
•
When the SCI is receiving 9-bit characters, R8 is the read-only ninth
bit (bit 8) of the received character. R8 is received at the same time
that the SCDR receives the other eight bits.
