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.

In order to activate the write protection mode, the WP bit in Table 10 must be logic high. To deactivate the write protection, the
command must be sent again, except with the WP in logic zero state. WP is reset to the deactivated mode if power is cycled off and on.
