a checking starts from the top of diagnosis check items list sequen-
tially. After a checking started, standard commander keys are ac-
cepted while a message or title is blinking, so that you can go to the
next job.

If Syscon Diagnosis is selected, a checking starts immediately, and

In the Syscon Diagnosis, intermittent blocks such as 0-ff, 500-5ff,
a00-aff, f00-fff, 1400-14ff, etc. (address) are checked. All of the
operation are done with standard commander keys, and a menu can-
not be selected but all items are checked. After result display, you
can only select either “continue to next item” or “cancel”, and con-
tinue and retry in case of written data error are not available.

IC093 (Syscon ROM)
n IC094 (Syscon RAM) collating check
Checking range: 0x01000000 - 0x0101ffff
IC093 (Syscon ROM) data (program codes) are transferred in DMA
mode in the unit of 64 bytes to the IC094 (Syscon RAM), then they
are read every 1 byte and compared with data in IC093. As the
Syscon RAM check is made by saving the data into internal RAM
(DMA transfer), the data are written and read every 64 bytes, and
interruption during that time is completely masked.
If compared data are not same, a checking is suspended, and error
code 05, its address, written data, and read data are displayed. Se-
lect the subsequent processing by pressing a key. As this check is
made through DMA transfer, if Repeat is selected, the data are trans-
ferred in DMA mode again to the block where this error occurred
and a checking is continued from the error address.

The Hard Reset signal is output, and after cancelling the reset,
whether DRV BUSY signal changes from “low” to “high” is
checked. The detection timing of DRV BUSY “low” is about 250
msec after the reset is cancelled. Also, whether the signal becomes
“high” later is checked.

“high” later is checked.
After confirming “high” or “low” of DRV BUSY signal 250 msec
after reset was cancelled, if the signal does not go “high” though
about 300 msec elapsed, the reset error 02 is output.
after reset was cancelled, if the signal does not go “high” though

Confirm the result, and to cancel checking, press [RETURN],
[MENU], or [POWER]. Or, to continue next checking, press other
than these keys.
The ROM revision and checksum of Drvcon are displayed when
executing “DrvCon Data Exchange” and “DrvCon EPROM” re-
spectively.
Also, in case of an error, the error code and information are dis-
played as shown in Figure 4.

(2-2) Syscon ROM (IC093) check
Calculation of checksum
Calculation range: 0x00000000 - 0x000fffff (at commercial prod-
ucts, 8Mbit ROM)
All 8bit data from address 0 to ROM size are added (checksum),
and output as 4-digit hexadecimal number.
In this check, the IC090 (Syscon) itself does not detect an error.
The result is displayed on the screen. Compare it with original ROM
checksum.
