Faults availability

All the results coming from I2C bus, by read operations, are the consequence of

measurements inside a defined period of time. If the fault is stable throughout the whole

period, it will be sent out.

To guarantee always resident functions, every kind of diagnostic cycles (Turn on,

Permanent, Offset) will be reactivate after any I2C reading operation. So, when the micro

reads the I2C, a new cycle will be able to start, but the read data will come from the previous

diag. cycle (i.e. The device is in Turn On state, with a short to Gnd, then the short is

removed and micro reads I2C. The short to Gnd is still present in bytes, because it is the

result of the previous cycle. If another I2C reading operation occurs, the bytes do not show

the short). In general to observe a change in Diagnostic bytes, two I2C reading operations

are necessary.
