10.6.4 SCI Status Register
MC68HC705C8A — Rev. 3
MOTOROLA
Address:
SBK — Send Break Bit
The SCI status register (SCSR) shown in
signal these conditions:
Reset:
Read:
Write:
idle input or an address mark brings the receiver out of the standby
state. Reset clears the RWU bit.
Setting this read/write bit continuously transmits break codes in the
form of 10-bit or 11-bit groups of logic 0s. Clearing the SBK bit stops
the break codes and transmits a logic 1 as a start bit. Reset clears the
SBK bit.
