state of the device when IGN, FOG, FLASHER, and
logic [0] (wake=0). In the Sleep mode, the outputs and all
internal circuitry are OFF to minimize current draw. In
addition, all SPI-configurable features of the device are reset.
The 10XS3535 will transit to two modes (Normal and Fail)
depending on wake and fail signals (see Fig13).

Freescale Semiconductor
The Sleep mode is the default mode of the 10XS3535.
The transition to the other modes is according following
• Wake = IGN or IGN_ON or FLASHER or
• Fail = VCC fail or SPI fail or External limp
