FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
faults. Timing between two write words must be greater than
the fault timer to allow adequate time to sense and report the
proper fault status.
SPI RESPONSE REGISTERS
Fault reporting is accomplished through the SPI interface.
All logic [1]s received by the MCU via the SO pin indicate
faults. All logic [0]s received by the MCU via Pin indicate no
.

19. These bits refer to command On or Off state in the command registers, not the state of the respective output lines. These bits are not to be
confused with the ignition mode state which is controlled only by the parallel inputs and their state is not reflected in these bits.
