Figure 30. Multi-Read
The fault register REG09 locks the previous fault and only clears it after the register is 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. To verify real time fault, the fault
register REG09 should be read twice to get the real condition. In addition, the fault register REG09 does not
support multi-read or multi-write.
