REG09 is a fault register. It keeps all the fault information from last read until the host issues a new read. For
example, if Charge Safety Timer Expiration fault occurs but recovers later, the fault register REG09 reports the
fault when it is read the first time, but returns to normal when it is read the second time. in order to get the fault
information at present, the host has to read REG09 for the second time. The only exception is NTC_FAULT
which always reports the actual condition on the TS pin. in addition, REG09 does not support multi-read and
multi-write.
