Detailed Block Diagram

All 16 channels can be controlled via the serial interface (SPI). In addition to the serial control it is possible to con-

trol channel 1 to 4 and 9 to 12 direct in parallel with a separate input pin. The parallel input signal is either ORed or

ANDed with the respective SPI data bit. This boolean operation can be programmed via SPI control byte (see

chapter "Functional Description"). The SPI interface also performs a diagnostic information for each channel.
