6.4.1 Active Resets from Internal Sources

MOTOROLA
NOTE:
An internal reset can be caused by an illegal address, illegal opcode,
COP timeout, LVI, POR, or MENRST as shown in
For LVI or POR resets, the SIM cycles through 4096 CGMXCLK cycles
during which the SIM asserts IRST. The internal reset signal then follows
with the 64-cycle phase as shown in
The COP reset is asynchronous to the bus clock.
