Bit Set

Set specified bit of stored integer to one

  • Bit Set block

Libraries:
Simulink / Logic and Bit Operations
HDL Coder / Logic and Bit Operations

Description

The Bit Set block sets the specified bit of the stored integer to one. Scaling is ignored.

You can specify the bit to be set to one with the Index of bit parameter, where bit zero is the least significant bit.

Ports

Input

expand all

Input signal with the specified bit of the stored integer.

Data Types: single | double | Boolean | fixed point

Output

expand all

Output signal with the specified bit set to 1.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus

Parameters

expand all

Index of bit where bit 0 is the least significant bit.
