Send Byte  
The Send Byte protocol is used to set the internal address register pointer to the correct address  
location. No data is transferred during the Send Byte protocol as shown in Table 4.4.

Receive Byte  
The Receive Byte protocol is used to read data from a register when the internal register address  
pointer is known to be at the right location (e.g. set via Send Byte). This is used for consecutive reads  
of the same register as shown in Table 4.5.
