Test Program for Field.

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
