Checking for Errors Error conditions are monitored and error codes are returned as indicated in
figure C-6.
Comments
• The registers used are:
– Status Register (base + 04
16
)
– Command Register (base + 08
16
)
– Query Response Register (base + 08
16
)
• Status Register bit 7 is monitored to determine when the previous
command has finished. Bit 6 is monitored to determine when a
configuration error has occurred.
• Once an error is detected, the error code is written to the Query
Response Register with the Send Error command (opcode 15).
• Status Register bit 1 is monitored to determine when the error code
can be read from the Query Response Register.
