Freescale Semiconductor, Inc. Hardware Peripheral Differences 2 Hardware Peripheral Differences The DSP56362 has many peripherals that should not be used when developing DSP56364 software. In Figure 1., we have highlighted the peripherals that should not be accessed on a DSP56362 because they do not exist on a DSP56364. 1 2 16 12 5 MEMORY EXPANSION AREA ADDRESS GENERATION PROGRAM RAM /INSTR.

Figure 1. DSP56362 and DSP56364 Differences Diagram. Triple Timers and DAX (SP/DIF) are core peripherals that should not be addressed. Other peripherals on the DSP56362 can be used to emulate the features of the DSP56364. For example, the DSP56362 HDI08 can be used to emulate the DSP56364 GPIO. 2 Developing DSP56364 Software Using the DSP56362 EVM For More Information On This Product, Go to: www.freescale.com
