3.5 Memory TestMemory Test		3 Tests and Diagnostics
Subtest 05	L2 Cache Memory
	To test the L2 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 L2 cache memory.
	Number of misses < Number of hits → OK
	Number of misses ≥ Number of hits → NG
	Read/Write/ Compare data directly by G.A. operation for the TAG-RAM.
Subtest 06	Stress
	This test prepares the write/read buffer (size:1b30h) and produce write date in
	the write buffer. The write data is written in the area larger than 1 MB and
	read into the read buffer then repeated to compare until maximum size.

Test data:

ffh, ffh, ffh, ffh, ffh 00h, 00h, 00h, 00h, 00h ffh, ffh, ffh, 00h, ffh 00h, 00h, 00h, ffh, 00h 00h, ffh, ffh, ffh, ffh 00h, 00h, 00h, 00h, aah

These data are generated repeatedly by 1b30h size.
