Description

This blocks sets the specified bit of the integer input to 0. The user can specify the bit in the field: "index of bit". Bit 0 is the least significant bit.

Dialog box

• Datatype(3=int32 4=int16 5=int8 ...)
  It indicates the type of the input/output data. It support all the integer datatype, number must be between 3 and 8.
  Properties : Type 'vec' of size 1.

• index of bit (0 is least significant)
  It indicate the index of the bit to clear. When the type is int32 or uint32 the number must be positive and less than 32. When the type is int16 or uint16 the number must be positive and less than 16. When the type is int8 or uint8 the number must be positive and less than 8.
  Properties : Type 'vec' of size 1.

Default properties

• always active: no
• direct-feedthrough: yes
• zero-crossing: no
• mode: no
• regular inputs:
  - port 1 : size [1,1] / type 3
  
• regular outputs:
  - port 1 : size [1,1] / type 3
  
• number/sizes of activation inputs: 0
• number/sizes of activation outputs: 0
• continuous-time state: no
• discrete-time state: no
• object discrete-time state: no
• name of computational function: bit_clear_32
