3.5 MEMORY TEST
Subtest 01
RAM constant data (Execution time: 58 seconds)
This test writes constant data to Memory, and then reads
and compares them with the original data. The constant
data are "FFFFH", "AAAAH", "5555H", "0101H" and "0000H".
Subtest 02
RAM address pattern data (Execution time: 17 seconds)
This test makes the segment address and offset address by
XORing, and then writes the address pattern data and reads
and compares them with the original data.
Subtest 03
RAM refresh (Execution time: 34 seconds)
This test writes constant data in 256 bytes length to
Memory, and then reads and compares it with the original
data. The constant data are "AAAAH" and "5555H". A certain
interval time will be taken between the write and the read
operations.
Subtest 04
Expansion bus (Execution time: 3 seconds)
