Filter Display Function

The filter display function narrows down frames shown in Monitor Window and Each ID Window.
Settings are configured in Display Filter Window.

• Select display targets
  In addition to specifying individual CAN IDs, detailed conditions such as range and exclusion can be configured.

This enables quick confirmation of only required frames from large amounts of data.

Or	(Log ID | ID1) = ID2	Matches when bitwise OR result equals ID2.	Show IDs with any target bits set.
Xor	(Log ID ^ ID1) = ID2	Matches when bitwise XOR result equals ID2.	Check bit inversion conditions.
Range	Log ID = ID1 ～ ID2	Matches IDs within range ID1 to ID2.	Show a block of IDs. Example: 0x100～0x1FF.
