The unit itself updates the contents of the latest log block area constantly, so it is not necessary to turn
on the error log notified request signal.

The error log notified request signal is turned on.
-
If the handshake is carried out through the I/O, Y2F is turned on.
-
If the handshake is carried out through the shared memory, bit F of address 368H in the request signal
area (bank 0) is turned on.
The error log is sent to the shared memory.
Check to make sure the error log notified complete signal is on.
-
If the handshake was carried out through the I/O, make sure that XF is on.
-
If the handshake was carried out through the shared memory, make sure that bit F of address 360H in
the complete signal area (bank 0) is on.
Read the log block read processing area (from addresses 390H) in the error log area of the shared
memory.
