18. Cache Test Mode
the external agent does the following:
- loads the mode bits into the processor by driving the mode bits (with the CTM mode bit negated) on SysAD(63:0)
- waits at least two SysClk cycles
- asserts SysGnt* for at least one SysClk cycle
After at least one SysClk cycle, the external agent may negate SysReset* to end the reset sequence.
Figure 18-2 shows the cache test mode exit sequence.
