4.5.6.1
Application Sequence for CPU Self-Test
1. Configure clock domain frequencies.
2. Select number of test intervals to be run.
3. Configure the timeout period for the self-test run.
4. Enable self-test.
5. Wait for CPU reset.
6. In the reset handler, read CPU self-test status to identify any failures.
7. Retrieve CPU state if required.
For more information see the RM48x Technical Reference Manual (SPNU481).
4.5.6.2
CPU Self-Test Clock Configuration
The maximum clock rate for the self-test is 100MHz. The STCCLK is divided down from the CPU clock.
This divider is configured by the STCCLKDIV register at address 0xFFFFE108.
For more information see the RM48x Technical Reference Manual (SPNU481).
4.5.6.3
CPU Self-Test Coverage
Table 4-7 shows CPU test coverage achieved for each self-test interval. It also lists the cumulative test
cycles. The test time can be calculated by multiplying the number of test cycles with the STC clock period.
