MCU INTERFACE DESCRIPTION
In operation, the 33880 functions as an eight-output serial
switch serving as a microcontroller (MCU) bus expander and
buffer, with fault management and fault reporting features. In
doing so, the device directly relieves the MCU of the fault
management functions. This device directly interfaces to an
MCU using a Serial Peripheral Interface (SPI) for control and
Master In Slave Out (MISO) line. On rising edge of CS data
stored in the input register is then transferred to the output
driver.

Figure 22. 33880 SPI System Daisy Chain
Multiple 33880 devices can be controlled in a parallel input
fashion using the SPI. Figure 23 illustrates 24 loads being
controlled by three dedicated parallel MCU ports used for
chip select.

Figure 22 illustrates the Daisy Chain configuration using
the 33880. Data from the MCU is clocked daisy chain through
each device while the Chip Select ( CS ) bit is commanded low
by the MCU. During each clock cycle output status from the
