No. of message bits needing to be truncated in previous MDW group
= Total message bits of previous MDW group - [ (lc15−lc0)_previous - (lc15−lc0)_current ]
ter flag in EDW
Status
ter = 1
long message is completed
ter = 0
long message is not completed

MDW Definition
The received paging message will be output as MDW1, MDW2 ....MDWn format (MDW group).
md17−md0 are the actual paging message data resolved from the message partition, including
terminator character EOM and any dummy bit such as a filler. For any submessage of a long message,
µC needs to use AIW's lc15−lc0 to truncate terminator or dummy bit from md17−md0 according to AIW
description. While remote programming, rd17−rd0 is used for remote programming data only. RPI is the
remote programming index received from system. This bit should be loaded into b147 of option bit
during the re-initialization stage if the remote address is programmed.

Table 34. MDW bit description
Any paging message such as 7 bit alphanumeric, 4 numeric or transparent data will be placed
continuously in the 18 bit information field, md17−md0. After the last character (or bit) of message the
following message termination procedures shall be used:
• Alphanumeric: an EOM character (0010001) shall be appended;
• Numeric: no terminating character required;
• Transparent data: a single bit set to one shall be appended;
