Normal Mode (1)
Arithmetic Mode
Counter Mode
LEs in normal mode support register packing.
There are two LAB-wide clock enables per LAB.
When using the carry-in in normal mode, the packed register feature is unavailable.
A register feedback multiplexer is available on LE1 of each LAB.
The DATA1 and DATA2 input signals can supply counter enable, up or down control, or register feedback signals for
LEs other than the second LE in an LAB.
The LAB-wide synchronous clear and LAB wide synchronous load affect all registers in an LAB.
