The Request RAM Test Report command allows the host to obtain detailed results of RAM
testing during the Continuous Integrity Test or automatic self-testing. The host receives a
response from this command while the Continuous Integrity Test is in progress only if the
Continuous Integrity Test was activated by the host rather than locally by the user.
The TCS responds to the Request RAM Test Report command by sending to the host the RAM
Test results obtained since the Continuous Integrity Test started or since the TCS was last
powered-up or reset.
'()$8/7
The test results are always reinitialized to zero at the start of the Continuous Integrity Test, when
power is applied, or when the TCS is reset.

<ESC>[>8n
The TCS responds with:
<ESC>[>8;<Ploops>;<Pfail>;<Paddr>;<Perror>;<Phistory>n
<Ploops> indicates the number of RAM Tests completed since the Continuous Integrity
Test started or since the TCS was last powered-up or reset.
<Pfail> indicates the number of RAM Tests that detected a failure since the Continuous
Integrity Test started or since the TCS was last powered-up or reset.
<Paddr> is the decimal equivalent of the last failed address. The value of <Paddr> is 0 if
no errors have been detected.
<Perror> is the decimal equivalent of the data value sent to the last failed address
exclusive-ORed with the data value received at the last failed address.
<Phistory> is the decimal equivalent of the data bit error history. The data bit error
history is a 16-bit word that a) contains a logic 0 in each bit position that has never
shown an error during all RAM testing and b) contains a logic 1 in any position that has
contained an error during RAM testing.
NOTE
The report may differ from the above format if the Reporting Formal command has been issued. Refer to
the Reporting Formal command description in Chapter 4 for details.
