ABSTRACT
The WFC3 Science Buffer RAM is checked for bit flips during SAA passages. This is followed by a Control Section (CS) self-test consisting of
writing/reading a specified bit pattern from each memory location in Buffer RAM. The CS Buffer RAM self-test as well as the bit flip tests are all
done with the CS in OPERATE.
OBSERVING DESCRIPTION
Using the set buffer memory macro, write zeros into CS Buffer RAM prior to passage into the SAA and then dump buffer memory to SSR after exit
from the SAA to check for bit flips. This Buffer RAM check should be executed several times, spanning the SAA. Then use the CS self test macro to
conduct a pattern test of CS Buffer RAM and check the memory fail counter after the test has completed.
The CS tests are done in OPERATE so that the CS paging is enabled and all 68 mega-bytes of memory are available for testing.
REAL TIME JUSTIFICATION
Realtime access to the engineering telemetry is needed to check the memory and to monitor the self test results in Visit 13.
ADDITIONAL COMMENTS
PREREQUISITES: Successful execution of proposal 11357 and subsequent verification of the dumps from that program.
...............................................................................
SCHEDULING: This program is to be scheduled 24-36 hours after 11357. Visits 01-06 should be scheduled in pairs, before and after the three

consecutive deepest SAA passages of a day. Visits 07-12 should be scheduled in the same manner the following day. The next WFC3 proposal,
11455 (UVIS CCD Activation), is to be scheduled 24-36 hours after this proposal is completed. All exposures in this proposal require Special
Commanding.

Comments: With the CS in Operate, perform a pattern read/write test of the CS Buffer RAM. Prior to the start of this test, set up memory monitors on the first 2 entries of the 10 entry Results Table (i.e., 3 monitor word
s per entry, starting at location IRSLFTST). The default patterns and values for the macro are OK so no patching is required. Note at the end of the test, each byte in CS Buffer memory will contain the test pattern ('55'
X). This should not pose a problem since ACCUM exposures will overwrite anything present (next Proposal 11455).
