PRODUCTION DATA
The µCRC module is part of the master subsystem. This module can be used by Cortex-M3 software to compute CRC on data and program, which are stored at memory locations that are addressable by Cortex-M3. On this device, the Cortex-M3 Flash Bank and ROM are mapped to the code space that is only accessed by the ICODE/DCODE bus of Cortex-M3; and RAMs are mapped on the SRAM space that is accessible by the SYSTEM bus. Hence, the µCRC module snoops both the DCODE and SYSTEM buses to support CRC calculation for data and program.
