Pack Boolean data into bitfields
Description
Specify whether Boolean signals are stored as one–bit bitfields or as a Boolean data type.
Category: Optimization
Note
You cannot use this optimization when you generate code for a target that specifies an explicit structure alignment.
Settings
Default: Off
On Stores Boolean signals into one–bit bitfields in global block I/O structures or DWork vectors. This will reduce RAM, but might cause more executable code.
OffStores Boolean signals as a Boolean data type in global block I/O structures or DWork vectors.
