Figure 19 OR Operation between IN and Serial Input
This OR operation enables the serial interface to switch the channel ON, even though the corresponding parallel
input might be in the off state.
SPI Priority for ON-State
Also parallel control of the outputs is possible without an SPI input.
The OR-function is the default Boolean operation if the device restarts after a Reset, or when the supply voltage
is switched on for the first time.
If the OR operation is programmed it is latched until it is overwritten by the AND operation.

With HHHH LLLL as the control word, each of the input signals IN1 to IN4 are ‘AND’ed with the corresponding SI
data bits.
With HHHH HHHH as the control word, each of the input signals IN9 to IN12 are ‘AND’ed with the corresponding
