IN 1...4/9...12

Serial Input,

data bits 0...3

This OR operation enables the serial interface to switch the channel ON, even though the cor-

responding 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.

5/10. HHHH XXXX DDDDDDDD - AND operation, and ‘full diagnosis’

With HHHH LLLL as the control word, each of the input signals IN1...IN4 are 'AND'ed with the

corresponding SI data bits.

With HHHH HHHH as the control word, each of the input signals IN9...IN12 are 'AND'ed with

the corresponding SI data bits.

IN 1...4/9...12

Serial Input,

data bits 0...3

The AND operation implies that the output can be switched off by the SPI data bit input, even

if the corresponding parallel input is in the ON state.

SPI Priority for OFF-state

This also implies that the serial input data bit can only switch the output channel ON if the cor-

responding parallel input is in the ON state.

If the AND operation is programmed it is latched until it is overwritten by the OR operation.
