diagnosis can be available for repeated use by sending the read command repeatedly after the initial

Writing
As initially, the write data is set when the on diagnostic cycle enable (IB1 D6 = 1), the turn on
Therefore, it is useful to check number of cycles from Power ON to the output appearance.
This IC has two built-in diagnostic modes dependent on the Turn-on timing.
A) Normal mode (one shot) of Turn-on diagnostics (data of IB1, D7 = 0)
B) Repeatability mode of Turn-on diagnostics (data of IB1, D7 = 1)
