Description
Use this command to verify that data written into the miscellaneous SRAMs in the ASIC are
retained after a 10 second wait.
The test method is to write a fill pattern to all SRAMs, wait 10 seconds, and then read all SRAMs
checking that data read matches data previously written. Then the test is repeated using the
complementary version of the pattern. The following patterns are used:
0xffffffff (and 0x00000000)
0x55555555 (and 0xaaaaaaaa)
0x33333333 (and 0xcccccccc)
