Configuring the Lookup Table
Output Filter
The lookup table in each LUT unit can generate any logic expression OUT as a function of up to
four inputs, IN[3:0]. The truth table for the expression is written to the TRUTH register for the
LUT.
and the corresponding input and outputs will be IN[4n] to IN[4n+3] and OUTn.
Table 29-2.
By default, the output OUTn is a combinatorial function of the inputs IN[4n] to IN[4n+3]. This may
cause some short glitches to occur when the inputs change value.
It is also possible to clock the output through a filter to remove glitches. This requires that the
corresponding generic clock (GCLK) has been enabled before use. The filter can then be
enabled by writing a one to the Filter Enable (FILTEN) bit in CRn. The OUTn output will be
delayed by three to four GCLK cycles when the filter is enabled.
