Event data also provide a validity bit for each data object, starting from register 408213. Bit
0 setting to be 1 indicates that the first data is valid for current trip unit style, bit 1 for the
second data object, bit 2 for the third data object and so on. The number of validity bit regis-
ters is calculated as (number of data objects - 1)/16.
The following registers are the data objects. Request out of the range of the registers
address would result in exception code 02.
