FUNCTIONAL DESCRIPTION
FUNCTIONAL DEVICE OPERATION
FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
As described below and depicted in Figure 1 below and
Normal, Sleep, and Stop. Operational modes are controlled
by MODE1 and MODE2 bits in the SPI Register (refer to
Logic Commands and Registers on page 24). In additional,
there are two transitional modes: Reset and Normal Request.
RESET MODE
At power up, the 33689 switches automatically to Reset
Mode for 1 ms if VDD goes high. If VDD stays low, after
150 ms the 33689 goes in Sleep Mode.
NORMAL REQUEST MODE
Before entering in Normal Request Mode, the 33689 stays
for 1 ms in Reset Mode. In this mode, the LIN bus can
transmit and receive information.

Legend
Watchdog Selected: External resistor between WDC pin and GND or WDC pin open.
Watchdog Not Selected: WDC pin connected to GND.
Watchdog Fail: Watchdog trigger occurs in closed window or no SPI Watchdog trigger command.
Stop Command: SPI stop command.
Sleep Command: SPI sleep request followed by SPI sleep command.
Wake-Up: L1 or L2 state change or LIN bus wake-up or CS rising edge.
