Definition
This pin provides connection to drain of output MOSFET number seven.
This pin provides connection to drain of output MOSFET number six.
This pin clocks the internal Shift registers of the 33298.
This pin is for the input of serial instruction data. SI information is read on the falling edge of
SCLK.
