4.3.1.2 INITIALIZING THE SCM68000 FOR SIMULATION. To simulate the SCM68000
properly, the initialization procedure differs slightly from the actual part. This difference is
necessary to correctly start the test clock (TESTCLK). Both HALTIB and RESETIB must be
asserted for at least 10 clock cycles. The TEST signal must be asserted for at least two clock
cycles while HALTIB and RESETIB are asserted and must be negated at least two clock
cycles before HALTIB and RESETIB are negated. Figure 4-13 shows the timing for initializ-
ing the SCM68000 for simulation.
If the SCM68000 has been properly reset during simulation, the TESTCLK signal will pulse
with a period equal to ten SCM68000 clock periods. The period will consist of six SCM68000
clock periods in the low position and four SCM68000 clock periods in the high position.
