How to reset AD779x sequencial channel reading

Can you tell me how to reset the sequencial channel reading of AD799x?


For instance, according to the datasheet, when D7 to D4 bits in the configuration register of AD7995 are all set to 1, AD7995 converts from CH0 to CH4 sequencially until the user keep sending read command via I2C. In this case, how the user can refresh the current reading channel during sequencial reading (e.g. before reading CH2 or 3) and re-start from CH0 reading? Does the user need to power cycle AD7995, or re-writing configuration register will refresh the current reading channel?
