4.7 Microcontroller Usage
Table 4-1
shows how much of memory is needed to run the 3-phase AC
drive in the speed closed loop. A significant part of the microcontroller
memory is still available for other tasks.
The MC68HC908MR32 microcontroller offers many features that
simplify the drive design. The following table describes individual
available blocks and their usage for the introduced system.
