Pattern Editing Conventions

When entering values in patterns the following conventions apply:

In Binary, 'X' means one bit which is “don't care” and the value can be either 1 or 0. Below are some examples in binary and their meanings:

“X10”: The value length is 3 bits and from right to left, the first and second bits have specific values and the third one is “don't care”.

“XXXXXXX1”: The value length is 8 bits and from right to left, the first bit has a specific value and the rest are “don't care”.

In Hexadecimal 'X' means 4 bits in which all four are “don't care”. In hexadecimal '?' means either one of the bits 1, 2, 3 or 4 bits is “don't care” and it is not clear which bit is “don't care” and which ones have specific value. Some examples are shown in the table below.

If VI_READ_RQST is selected, the value for the “Device HDR” field will be “10” in binary format as this field is a two-bits field. This field is the last field in the “DF_CTL” field which is an 8 bits field. For this specific frame, the value of “DF_CTL” will be “XXXXXX10” in binary format and “X?” in hexadecimal format according to the conventions above.
