In code generation, for ports and bus that only transmit boolean data, how to make them appeared as bitfields in the generated code? The documents give an example for parameters, but there seems no way for signals.

When you select the model configuration parameter Pack Boolean data into bitfields, Embedded Coder packs the Boolean signals into 1-bit bitfields in global block I/O structures or DWork vectors. This will reduce RAM consumption, but might cause more executable code.This option is available under Model Configuration Parameters:
Code Generation > Optimization > Optimization Levels > Details > Pack Boolean data into bitfields
Also select the option Specify custom optimizations under Optimization Levels section.
Selecting Pack Boolean data into bitfields enables model configuration parameter Bitfield declarator type specifier. Select appropriate Bitfield declarator type specifier.
Please refer following MATLAB Documentation link for more information:
Hence boolean signals generated from inport and going towards outport can be packed into 1-bit bitfields whereas inports and outports will not be appeared as bitfields in generated code.
