In this mode, ROM revision number (Ver. No.) of each control IC
(MPU) and its checksum are displayed. However, Syscon checksum
and Drvcon value are obtained in the process of diagnosis check,
and therefore they are initially 0.
On the fifth line, an item is displayed, and IF control information is
displayed at the bottom though it is not related to a checking of
each item.
If Syscon Diagnosis is selected, a checking starts immediately, and
the result of initial ROM check and Syscon ROM checksum are
displayed as shown in Figure 3.
