33. Care must be taken when using this Special Character code. When a C7.0 or C0.7 is followed by a D11.x or D20.x, an alias K28.5 sync character is created.

These sequences can cause erroneous framing and should be avoided while RFEN is HIGH.

allows construction of X3.230:1994 “EOF” frame delimiters wherein the second data byte is determined by the Current RD.
For example, to send “EOFdt” the controller could issue the sequence C2.1−D21.4− D21.4−D21.4, and the HOTLink Transmitter will send either
K28.5−D21.4−D21.4−D21.4 or K28.5−D21.5− D21.4−D21.4 based on Current RD. Likewise to send “EOFdti” the controller could issue the sequence
C2.1−D10.4−D21.4−D21.4, and the HOTLink Transmitter will send either K28.5−D10.4−D21.4− D21.4 or K28.5−D10.5−D21.4− D21.4 based on Current RD.
The receiver will never output this Special Character, since K28.5 is decoded as C5.0, C1.7, or C2.7, and the subsequent bytes are decoded as data.
Character has the same effect as asserting TXSVS = HIGH. The receiver outputs this Special Character only if the Transmission Character being decoded is
not found in the tables.
running disparity. The receiver will output C1.7 if −K28.5 is received with RD+, otherwise K28.5 is decoded as C5.0 or C2.7.
disparity. The receiver will output C2.7 if +K28.5 is received with RD−, otherwise K28.5 is decoded as C5.0 or C1.7.
Character being decoded is found in the tables, but Running Disparity does not match. This may indicate that an error occurred in a prior byte.
