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 T
LIM
.
Bits 8 to 15 will always return “0”.
