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
