lines (TXD/RXD) data encoding/decoding will be possible. Connecting together the LUT units, RS Latch or any
combinatorial logic between two operands or three inputs can be enabled.
The LUT works in all sleep modes. Combined with event system and one I/O pin, the LUT can wake-up the system if, and
only if, condition on up to 3 input pins is true.
A block diagram of the programmable logic unit with extensions and closely related peripheral modules (in grey) is shown
in Figure 26-1.
