8.7.8.1
General
The message field follows the vector field in the FLEX
protocol. It contains the message data, checksum
information, and may contain fragment and message
numbers (Sections 8.8.8 and 8.8.6). If the error bit of a
vector word is not set and the vector word indicates that
there are message words associated with the page, the
message words are sent in message packets to the host.
The ID of the message packet is the word number where
the message word was received in the frame.
WN:
word number of message word (3 to 87 decimal)
(Table 49). WN describes the location of the message
word in the frame.
e:
error (Table 49). Set if more than 2-bit errors are
detected in the word.
p:
phase (Table 49). This is the phase on which the vector
was found (0 = A, 1 = B, 2 = C and 3 = D).
i:
these are the information bits of the message word
(Table 49). The definition of these i bits depends on the
vector type and which word of the message is being
received.
8.7.8.2
Numeric Message
FLEX
numeric messages are encoded using the
4-bit BCD encoded characters sets described in Table 48.
Characters are placed in codewords along with additional
information about the message as described in
Tables 50 and 51 and the following definitions. The 4-bit
numeric characters of the message are designated as
letters a, b, c, d, ... z, A, B etc.
Only codewords containing the numeric message are to
be transmitted. The space character CH is used to fill any
unused 4-bit characters in the last word and zeros to fill
any remaining partial characters. The checksum includes
only the codewords comprising the shortened message,
along with the space and fill characters used to fill in the
last word.
