AD8120 Register Read/Write sequence

Question

Another question on the AD8120. 
 
 Can the I2C registers be read/written sequentially (i.e., Address auto-increment, as in asking for the first register by memory address and have sequential reads/writes directly access the next sequential register)? Of course, this also follows a successful ACK responses. 
 
 Best regards,

Hi, 
 Yes,I2C read/write operation done in sequential manner with ack. In I2C mode, the AD8120 is programmed with a 3-byte sequence for a write operation(Figure 19) and a 4 byte sequence for a read operation (Figure 20). Please cross check with reference script. And also check I2c timing diagram in AD8120 datasheet manual. 
 
 Thanks,
