[FAQ] BQ25600: Why do I have to read the fault status twice to see the cleared fault on BQ2560x?

Tool/software:

When a fault occurs on BQ2560x (excluding BQ25606) an /INT pulse is sent to the host. For the BQ25601/D and BQ25600/C/D the fault statuses in REG0x09 are kept static until the host reads the registers. Before reading the status, no new /INT pulses are sent. To see the new current status, REG0x09 has to be read twice, the first being the old status and the second being the new status.
