CPU Self-Test Clock Configuration
The maximum clock rate for the self-test is 45MHz. The STCCLK is divided down from the CPU clock,
when necessary. This divider is configured by the STCCLKDIV register at address 0xFFFFE108.
when necessary. This divider is configured by the STCCLKDIV register at address 0xFFFFE108.

4.4.6.3
CPU Self-Test Coverage
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.
