I2C BYTE FORMATS
The following generic, write, read, and store/restore control
registers for the AD5258 refer to the device addresses listed in
Table 5, and following is the mode/condition reference key.
S = Start Condition
P = Stop Condition
SA = Slave Acknowledge
MA = Master Acknowledge
NA = No Acknowledge
W = Write
R = Read
X = Don’t Care
AD1 and AD0 are two-state address pins.
