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.

Stress
Data (from 1MB to the maximum MB) is written from the 16KB write buffer
to the 16KB read buffer and compared the data in the buffers. The read buffer
starts from 0001 and the comparison is continued with the following read
buffer addresses: 0001, 0003, 0005, 0007, 0009, 000b, 000d and 000f.
