4.5.4
Duplicate clock tree after GCLK
The CPU clock domain is split into two clock trees, one for each CPU, with the clock of the 2nd CPU
running at the same frequency and in phase to the clock of CPU1. See Figure 4-3.
4.5.5
ARM Cortex-R4F
CPU Compare Module (CCM) for Safety
This device has two ARM Cortex-R4F
CPU cores, where the output signals of both CPUs are compared
in the CCM-R4 unit. To avoid common mode impacts the signals of the CPUs to be compared are delayed
in a different way as shown in the figure below.
Figure 4-3. Dual Core Implementation
To avoid an erroneous CCM-R4 compare error, the application software must initialize the registers of
both CPUs before the registers are used, including function calls where the register values are pushed
onto the stack.
4.5.6
CPU Self-Test
The CPU STC (Self-Test Controller) is used to test the two Cortex-R4F CPU Cores using the
Deterministic Logic BIST Controller as the test engine.
The main features of the self-test controller are:
Ability to divide the complete test run into independent test intervals
Capable of running the complete test as well as running few intervals at a time
Ability to continue from the last executed interval (test set) as well as ability to restart from the
beginning (First test set)
Complete isolation of the self-tested CPU core from rest of the system during the self-test run
Ability to capture the Failure interval number
Timeout counter for the CPU self-test run as a fail-safe feature
