Parameter and type
Data type
Description
STARTCOND IN UInt Specifies the start condition (Default value: 1)
• 01H - Start Char
• 02H - Any Char
• 04H - Line Break
• 08H - Idle Line
• 10H - Sequence 1
• 20H - Sequence 2
• 40H - Sequence 3
• 80H - Sequence 4
IDLETIME IN UInt The number of bit times required for idle line timeout. (Default value:
40). Only used with an idle line condition. 0 to 65535
STARTCHAR IN Byte The start character used with the start character condition. (Default
value: B#16#2)
SEQ[1].CTL IN Byte Sequence 1 ignore/compare control for each character: (Default
value: B#16#0)
These are the enabling bits for each character in start sequence
• 01H - Character 1
• 02H - Character 2
• 04H - Character 3
• 08H - Character 4
• 10H - Character 5
Disabling the bit associated with a character means any character
will match, in this sequence position.
