Description

Control of the CS1112 can be done using the Serial Peripheral Interface (SPI) port using the Data Input information in Table 1, or the outputs can be controlled via the parallel inputs (IN0, IN1, IN2, IN3). IN0 controls OUT0, IN1 controls OUT1, IN2 controls OUT2, and IN3 controls OUT3. Turning the output drivers on is an OR function with the SPI input and the parallel inputs.

Note: To prevent damage to the IC or the output load, VDD must be above the Power on Reset threshold (3.5 V) before IN0, IN1, IN2, or IN3 are asserted high (< 70% VDD).
