(a) Checking hardware test results
1.
When the hardware test is completed, Hardware test completion status (SB0090) is turned on.
2.
When failed, Hardware test normal/abnormal end (SB0091) is turned on.
(b) Checking self-loopback test results
1.
When the self-loopback test is completed, Self-loopback test completion status (SB0092) is turned
