Serial Communications Interface (SCI)
MOTOROLA
If the receiver detects that a break (RDRF = 1, FE = 1, receiver data
register = $003B) produced the framing error, the start bit will not be
artificially induced and the receiver must actually detect a logic 1 before
the start bit can be recognized (see Figure 9-7).
Figure 9-7. SCI Start Bit Following a Break
9.11 Transmit Data Out (TDO)
Transmit data is the serial data from the internal data bus that is applied
through the SCI to the output line. Data format is as discussed in
9.7 Data Format and shown in Figure 9-3. The transmitter generates a
bit time by using a derivative of the RT clock, thus producing a
transmission rate equal to 1/16th that of the receiver sample clock.
9.12 SCI I/O Registers
These I/O registers control and monitor SCI operation:
SCI data register (SCDR)
SCI control register 1 (SCCR1)
SCI control register 2 (SCCR2)
SCI status register (SCSR)
