Hello,
The watchdog timer is used as a safety measure in case of MCU hang-up. When no I2C transaction is made within 50s, all registers except MRRESET_VIN and MRREC will be reset. This can be disabled by placing the charger in Hi-Z mode.
I2C will reset if SDA is held low longer than tI2CReset to avoid I2C hang-ups.
THiz_Activebat is the time is the time delay required between entering active BAT and the start of I2C transactions.
