FUNCTIONAL DESCRIPTION
DEVICE CONTROL USING CONFIGURATION PINS
Figure 28 illustrates and Table 2 lists the CDCUN1208LP device settings using the configuration pins. Some pins
sense three different states (HIGH, LOW, OPEN) according to Figure 28 and DIGITAL INPUT ELECTRICAL
CHARACTERISTICS – OE (SCL), INSEL, ITTP, OTTP, DIVIDE (SDA/MOSI), ERC(ADDR/CS), MODE. The
device samples the state of the pins at power up and configures the device accordingly. Certain pins including
INSEL and OE are sampled continuously; thus changes of state of INSEL or OE controls the device instantly.
