Notes
40.All codes not shown are reserved.
41.Notation for Special Character Code Name is consistent with Fibre Channel and ESCON naming conventions. Special Character Code Name is intended to
describe binary information present on I/O pins. Common usage for the name can either be in the form used for describing Data patterns (i.e., C0.0 through
C31.7), or in hex notation (i.e., Cnn where nn = the specified value between 00 and FF).
42.Both the Cypress and alternate encodings may be used for data transmission to generate specific Special Character Codes. The decoding process for received
characters generates Cypress codes or Alternate codes as selected by the BOE[7:0] configuration inputs.
43.These characters are used for control of ESCON interfaces. They can be sent as embedded commands or other markers when not operating using ESCON
protocols.
44.The K28.5 character is used for framing operations by the receiver. It is also the pad or fill character transmitted to maintain the serial link when no user data is
available.
45.Care must be taken when using this Special Character code. When a C7.0 or a 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 RFENx = 1.
46.C2.1 = Transmit either –K28.5+ or +K28.5– as determined by Current RD and modify the Transmission Character that follows, by setting its least significant bit
to 1 or 0. If Current RD at the start of the following character is plus (+) the LSB is set to 0, and if Current RD is minus (–) the LSB becomes 1. This modification
allows construction of X3.230 “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 sends 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 sends either K28.5–D10.4–D21.4– D21.4 or K28.5–D10.5–D21.4–D21.4 based on Current RD.
The receiver never outputs this Special Character, since K28.5 is decoded as C5.0, C1.7, or C2.7, and the subsequent bytes are decoded as data.
47.C0.7 = Transmit a deliberate code rule violation. The code chosen for this function follows the normal Running Disparity rules. Transmission of this Special
Character has the same effect as asserting TXSVS = HIGH. The receiver only outputs this Special Character if the Transmission Character being decoded is
not found in the tables.
48.C1.7 = Transmit Negative K28.5 (
K28.5+) disregarding Current RD. The receiver only outputs this Special Character if K28.5 is received with the wrong running
disparity. The receiver outputs C1.7 if
K28.5 is received with RD+, otherwise K28.5 is decoded as C5.0 or C2.7.
49.C2.7 = Transmit Positive K28.5 (+K28.5
) disregarding Current RD. The receiver only outputs this Special Character if K28.5 is received with the wrong running
disparity. The receiver outputs C2.7 if +K28.5 is received with RD
, otherwise K28.5 is decoded as C5.0 or C1.7.
50.C4.7 = Transmit a deliberate code rule violation to indicate a Running Disparity violation. The receiver only outputs this Special Character if the Transmission
Character being decoded is found in the tables, but Running Disparity does not match. This might indicate that an error occurred in a prior byte.
