	Fault Log Messages

		Fault Log Messages
0	Unknown Fault	This error message occurs when the fault could not be determined.
1	I2C: Timeout	This error message occurs if the A7 CPU assembly’s IIC controller takes too long to tell the
		MPU that it is ready for a new command.
2	I2C: No Device	This error message occurs if the A7 CPU assembly’s IIC controller does not sense the
	Acknowledge	acknowledge part of the formal handshake used to transmit data over the IIC bus.
3	Calibration failure	This error message occurs if the calibration routine generates correction vectors that exceed the
		maximum allowable error vectors or if the calibration routine is bypassed because of a
		hardware failure.
4	ROM	This error message occurs if the power-on test detects a ROM checksum error.
	Checksum error
5	BOOTROM	This error message occurs if the power-on test detects a BOOTROM checksum error.
	Checksum Error
6	DSP Failure	This error message occurs if the power-on digital signal processor test fails.
7	Main RAM Error	This error message occurs if the power-on RAM test fails.
8	Math	This error message occurs if the power-on math coprocessor test fails.
	Coprocessor
	Failure
9	LED Error	This error message occurs if the power-on LED test fails.
10	Display Failure	This error message occurs if the power-on display test fails.
11	CPU Failure	This error message occurs if the power-on CPU test fails.
12	Floppy Controller	This error message occurs if the A7 CPU assembly’s disk drive controller did not respond
	Timeout	within 10 ms of receiving a command.
13	Internal Disk	This error message occurs if the A100 Disk Drive assembly did not locate track 0 (as indicated
	Trk0 Failure	by a low on T00n) when instructed by the A7 CPU assembly to move to track 0.
14	NVRAM or	This error message occurs if the A7 CPU assembly’s IIC Controller determined that the A8
	Battery Backup	Memory assembly’s non-volatile RAM or RAM battery power failed.
	Failure
