FLEX
Pager Decoder
PCD5008
K:
10-bit fragment checksum (Tables 44 and 45).
See Section 8.8.6 for a description of message checksum.
C:
1-bit message continued flag (Tables 44 and 45).
When this bit is set, fragments of this message are to be
expected in following frames. See Section 8.8.5 for a
description of message fragmentation.
F:
2-bit message fragment number (Tables 44 and 45).
This is a modulo 3 message fragment number which is
incremented by 1 in successive message fragments.
See Section 8.8.5 for a description of message
fragmentation.
N:
message number (Tables 44 and 45). See
Section 8.8.7 for a description of message numbering.
M:
1-bit mail drop flag (Table 44). When this bit is set, it
indicates the message is to be stored in a special area in
memory and is written over existing data automatically in
that memory space.
R:
message retrieval flag (Table 44). When this bit is set,
the pager expects this message to be numbered.
See Section 8.8.7 for a description of message
numbering.
S:
7-bit signature field (Table 44). The signature is defined
to be the 1’s complement of the binary sum over the total
message (all fragments). 7 bits at a time are taken (on
alpha character boundary) starting with the first 7 bits
directly following the signature field, a

, etc. The 7 LSBs of the result are
transmitted as the message signature.
U, V:
fragmentation control bits (Table 45). This field exists
in all fragments except the first fragment. It is used to
support character position tracking in each fragment when
symbolic characters (character made up of 1, 2 or 3
ASCII characters) are transmitted using the alphanumeric
message type. The default value is 0,0.
See Section 8.8.5.1 for a description of fragment control.
Table 44
Vector type V = 101 first fragment
Table 45
Vector type V = 101 other fragments
