To avoid common mode impacts the signals of the CPUs to be compared are delayed in a different way as shown in the following figure. Figure 4-2. Dual Core Implementation 4.9.2 CCM-R4 To avoid an erroneous CCM-R4 compare error, the application software must ensure that the CPU registers of both CPUs are initialized with the same values before the 1st function call or other operation that pushes the CPU registers onto the stack. All CCM-R4 error forcing test modes are limited to 100MHz HCLK speed.
