5. Address pattern test
“16 bit write and 16 bit read” of address pattern data is executed and
the new data is compared with the original data.
Test data = 0000H, 0004H, 0008H, 000CH,...8000H, 8004H, through
FFECH
Subtest 02 Protected Mode
This subtest first writes data patterns and address data from 1 to 32 MB, then
reads the new data and compares the result with the original data patterns.
Addresses are displayed in 64KB increments during the test.
. Test Process:
1. Byte Enable Test
One bit write/ 8 bit read” is executed and the new data is compared
with the original data.
Test data = CCAA5533H, 80000000H
2. Byte Enable Test
“One bit write/16 bit read” is executed and the new data is compared
with the original data.
Test data = CCAA5533H, 80000000H
3. Data bus test
“One bit write/16 bit read” is executed and the new data is compared
with the original data.
Test data = 1H, 2H, 4H, 8H, 10H, through 80000000H.
4. Fixed data test
“16 bit write/ 16 bit read” is executed and the new data is compared
to the original data.
Test data = FFFFFFFFH, 00000000H, 80018001H
5. Address pattern test
“16 bit write and 16 bit read” of address pattern data is executed and
the new data is compared with the original data.
Test data = 0000H, 0004H, 0008H, 000CH,...8000H, 8004H, through
FFECH
Subtest 03 Protected Mode [32MB - MAX]
This subtest first writes data patterns and address data from 32MB to the
maximum installed memory, reads the new data, and then compares the result
