In compare match test, patterns are applied such that no compare error is generated. Because the comparison is done against the clamped values, and all compared signals are clamped to zero, only one test pattern is applicable for compare match test. A pattern of 'all-zeros' is applied for compare match test. If a compare mismatch is found, then self test error flag (STE3) is set and self test error is asserted. If an error is detected during compare match, then CCMR5 enters compare mismatch mode before terminating the test. If no mismatch is found, compare mismatch test is done next.
