I2C-COMPATIBLE FORMAT
The following generic, write, read, and store/restore control
registers for the AD5259 all refer to the device addresses listed
in Table 5; the mode/condition reference key (S, P, SA, MA,
NA, W, R, and X) is listed below.
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.
