摘要: An integrated circuit chip includes a mainline function logic path communicatively connected to a first input/output (I/O) pin, a test logic path communicatively connected to the first I/O pin, a latch disposed between the communicative connection between the test logic function path and the first I/O pin, a second I/O pin communicatively connected to the latch, the second I/O pin operative to send a signal operative to change a state of the latch.
