17 / 24 page  Analog Integrated Circuit Device Data Freescale Semiconductor 17 33879 FUNCTIONAL DESCRIPTION SPI DEFINITION Figure 17. Parallel Input SPI Control SPI DEFINITION On each SPI communication, a 16-bit command word is sent to the 33879 and a 16-bit status word is received from the 33879. The MSB is sent and received first. As Table 6 shows, the Command Register defines the position and operation the 33879 will perform on rising edge of CS. The Fault Register, shown in Table 7, defines the previous state status of the output driver. Table 8 identifies the type of fault and the method by which the fault is communicated to the microprocessor. Table 6. Command Register Definition 0 = Bits 0 to 7, Output commanded OFF. 0 = Bits 8 to 15, Open Load Detection Current OFF. 1 = Bits 0 to 7, Output commanded ON. 1 = Bits 8 to 15 Open Load Detection Current ON. Table 7. Fault Register Definition 0 = Bits 0 to 7, No Fault at Output. 1 = Bits 0 to 7, Output Short-to-Battery, Short-to-GND, Open Load, or TLIM. Bits 8 to 15 will always return “0”.
