Logic and Bit Operations

The Bit Clear block sets the specified bit, given by its index, of the stored integer to zero. Scaling is ignored.
You can specify the bit to be set to zero with the Index of bit parameter, where bit zero is the least significant bit.
The Bit Clear block supports Simulink integer, fixed-point, and Boolean data types. The block does not support true floating-point data types or enumerated data types.

If the Bit Clear block is turned on for bit 2, bit 2 is set to 0. A vector of constants 2.^[0 1 2 3 4] is represented in binary as [00001 00010 00100 01000 10000]. With bit 2 set to 0, the result is [00001 00010 00000 01000 10000], which is represented in decimal as [1 2 0 8 16].
