BitStuff
BitStuff (fieldId, bit);
Remark:
This statement preforms a bit-unstuffing algorithm on the field before the field
is interpreted. This statement is only required for high-level data of some
protocols. Do not confuse it with the low-level bit-unstuffing of USB. The
hardware bit-unstuffs USB traffic before presenting the data stream to the
decoder.
Input Parameters:
fieldId: This is the identifier that specifies the field. This
identifier is the output of a AddField statement.
bit: Specifies the number of consecutive 1’s before data is
bit-stuffed with a zero by the protocol. For example,
specifying this statement with this value being 5
converts the following stream “111110111b” into
“11111111b”.
Example:
/* run the bit-unstuff algorithm on 5 bits of continuous 1s */
Data = AddField(8, 16,"Data","Data","");
BitStaff(Data,5);
