3.5 Memory Test		3 Tests and Diagnostics
Subtest 04	Cache Memory
	To test the cache memory, a pass-through write-read comparison of ‘5A’ data
	is run repeatedly to the test area (‘7000’:‘Program’ size to ‘7000’:‘7FFF’ (32
	KB)) to check the hit-miss ratio (on/off status) for CPU cache memory. One
	test takes 3 seconds.
	Number of misses < Number of hits → OK
	Number of misses ≥ Number of hits → Fail
Subtest 05	L2 Cache Memory
	To test the L2 cache memory, a test similar to that for the cache memory is
	performed.
Subtest 06	Stress
	The conventional memory is provided with a write/read buffer (size 1b30 h)
	and creates write data in the write buffer. Subsequent to 1 MB, the data is
	written in the write buffer and is read into the read buffer, followed by a data
	comparison up to the maximum memory size.
