If a compare error occurs, the write data, read data, and test address display on the screen. Addresses are displayed in 4KB 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
