9.5.1.7 Multi-Read and Multi-Write
The charger device supports multi-read and multi-write on REG00 through REG0B.
Figure 9-18 Multi-Write
Figure 9-19 Multi-ReadREG09 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.
