Power supply pin to the SO output driver.
Battery supply input pin.
Ground for logic, analog, and power output devices.
System Clock for internal shift registers of the 33996.
SPI control chip select input pin from the MCU to the 33996.
Serial data input pin to the 33996.
Serial data output pin.
Active low reset input pin.
PWM control input pin. Supports PWM on any combination of outputs.
Device will perform as specified with the Exposed Pad un-terminated
(floating) however, it is recommended that the Exposed Pad be
terminated to system ground.
