Test Number: 8
Function: This test ensures that the VCACHE card flushes data correctly.
Procedure: In virtual mode and the VCACHE disabled, write memory with the first test
pattern using word accesses. Enable the VCACHE card and confirm that the
first test pattern was written into memory (this should load VCACHE). Disable
the VCACHE card and write the second test pattern. Enable the VCACHE card
and confirm that the first test pattern is present in the VCACHE card. Flush
the VCACHE card, read memory, and confirm that the second test pattern is
now read.
Hardware Tested: The MPB VCACHE card is tested.
Data Returned: The failing test number, the failing address, the expected pattern, and the
pattern are returned.
Notes: None
