4.2

Write Byte

The Write Byte is used to write one byte of data to the registers as shown below Table 4.2:

SLAVE

START ADDRESS

WR

1 -> 0

1001_100

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.
