sramRetentionTest
Figure 4-7 shows the
sramRetentionTest
command, which verifies that data
written into the ASIC memories are retained and that data bits do not decrease
when read after some amount of delay since the write.
IMPORTANT:
This test cannot be executed on an operational switch. Before issuing the
sramRetentionTest command, disable the switch using the switchDisable command.
