Figure 3-17: Pattern editor for 14-bit pattern in hexadecimal format
The maximum length of the pattern is 32 bit, however you can reduce the number of
bits. The available bits are initially indicated by 'X', while the unused bits are indicated
by gray squares. An 'X' indicates that the logical level for the bit is not relevant (do not
care). Once you enter a value for the selected bit, the 'X' is overwritten.
You can enter the pattern in binary or hexadecimal format. Depending on which bit you
select in the pattern display, binary or hexadecimal format is automatically selected for
input. In binary format, each bit is defined individually, and only the digits 0 and 1 are
available for input. In hexadecimal format, 4 bits are defined at the same time by the
selected hexadecimal value. If fewer than 4 bits are available (due to the total number
of bits), only those hexadecimal values are available that can be defined with the
remaining number of bits. For example, for a total number of 14 bits, 3x4 bits can be
defined by any hexadecimal value. The remaining 2 bits can define a 0, 1, 2, or 3 (as
shown in Figure 3-17).
To store the defined pattern, select "Enter". The pattern editor is closed and the pattern
is inserted in the pattern settings field.
