*ROM CORR data confirm
The following processings are performed in order to prevent that fault occurs, when a new micon / the old micon / ROM collection is
intermingled.
The data (ID) which a micon should make a judgment standard is stored in a [E2PROM] start address [2 bytes].
A data format presupposes that it is free (the version of the data which can be differentiated etc. is desirable).
When the [ROM coll data area] of [E2PROM] is read at the time of a reset start and data exists, it processes by judging whether it is
by the [ROM coll] data which should be applied.
In the case of the data which should be applied [good] : It progresses to the following step by un-processing.
In the case of the data which should be applied and which does not come out, it is [no] : All the [ROM coll data area] of [E2PROM] is cleared (FF).
