11.2.2. Enabling sections of the core

Three Cortex-A8 signals control whether or not sections of the processor can update when MBISTMODE is asserted or when TESTMODE is asserted. These signals are:

When either of these modes is asserted:

If these signals are HIGH, then the flip-flops that they control are allowed to update. When both MBISTMODE and TESTMODE are negated, the values of the TESTEGATE, TESTNGATE, and TESTCGATE inputs are not used.
