A WAKEUP command was issued with interrupts
enabled, but no interrupt occurred within a rea-
sonable time. The opcode of the packet command
issued replaces "cc" (hexadecimal).
After the start-up procedure, diagnostics will display error
messages if the SMD Controller returns ending-status (ES),
status-bits (SB) or Drive-Status (DS) fields indicating an
error occurred during command execution. These messages
have the following three fields:
1) Error Description Field - this field explains the end-
ing status (ES) code returned as well as any other
applicable error bits in DS and SB.
2) Operation Field - this field explains what type of
operation was being done when the error occurred.
3) Disk Address Field - this field shows what disk address
was being accessed when the error occurred. When a
multi-sector transfer command is given to the con-
troller, the Disk Address Field shows the START sector
addrE~ss
.
NOTE
The error may have occurred in a sector other than
the start sector.
The following tables show what values may appear in the
Error Description Field and the Disk Address Field. The
contents of the Operation Field vary from diagnostic to
diagnostic and are shown in the documentation for each diag-
nostic.
