4.3.2 Single-Wire Bus Transactions

Types of data transmitted over the SI/O line:

• Reset and Discovery Response
• Logic ‘0’ or Acknowledge (ACK)
• Logic ‘1’ or No Acknowledge (NACK)
• Start condition
• Stop condition

The Reset and Discovery Response is not considered to be part of the data stream to the device, whereas, the remaining four transactions are all part of the data sequence being sent to or received from the device. The difference between the types of data stream transactions is the duration that SI/O is driven low within the bit frame.
