BQ25120 watchdog timer

Other Parts Discussed in Thread: BQ25120

 请问,我公司现在用BQ25120遇到一些问题,发现数据手册里有一段这样的描述:

In addition to the safety timer, the device contains a 50-second watchdog timer that monitors the host through the I 2C interface. Once any I 2C transaction is performed on the I 2C interface, a watchdog timer is started. The watchdog timer is reset by any transaction by the host using the I 2C interface. If the watchdog timer expires without a reset from the I 2C interface, all registers except MRRESET_VIN and MRREC are reset to the default values

这个  watchdog timer 如何关闭,如果不关闭,当我IIC不操作时候,会不会每隔50S发生一次复位。
