INTERFACE DESCRIPTIONS
I
All control and access to both EEPROM memory and the
RDAC registers are conducted via a standard 2-wire I
Figure 2 shows the timing characteristics of the I
Figure 16 and Figure 17 illustrate standard transmit and receive
bus signals in the I
These figures use the following legend:
S = Start condition
P = Stop condition
A = Acknowledge (SDA low)
A = Not acknowledge (SDA high)
R/ W = Read enable at high and write enable at low
