8.3.2 LUT
The CY8C38 family of devices contains four LUTs. The LUT is a
two input, one output lookup table that is driven by any one or
two of the comparators in the chip. The output of any LUT is
routed to the digital system interface of the UDB array. From the
digital system interface of the UDB array, these signals can be
connected to UDBs, DMA controller, I/O, or the interrupt
controller.
The LUT control word written to a register sets the logic function
on the output. The available LUT functions and the associated
control word is shown in
