(1) A type change represents a major functional feature difference in a peripheral module. Within a peripheral type, there may be minor differences between devices that do not affect the
basic functionality of the module. These device-specific differences are listed in the C2000 Real-Time Control Peripherals Reference Guide and in the peripheral reference guides.
(2) TMS320F28027F and TMS320F28026F are InstaSPIN-FOC-enabled MCUs. For more information, see Section 8.4 for a list of InstaSPIN Technical Reference Manuals.
