FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
908E624 ANALOG DIE MODES OF OPERATION
The 908E624 offers three operating modes: Normal (Run),
Stop, and Sleep. In Normal mode the device is active and is
operating under normal application conditions. The Stop and
Sleep modes are low-power modes with wake-up
capabilities.
In Stop mode, the voltage regulator still supplies the MCU
with VDD (limited current capability), and in Sleep mode the
voltage regulator is turned off (VDD = 0 V).
Wake-up from Stop mode is initiated by a wake-up
interrupt. Wake-up from Sleep mode is done by a reset and
the voltage regulator is turned back on.
The selection of the different modes is controlled by the
MODE1:2 bits in the SPI Control register.
Figure 11 describes how transitions are done between the
different operating modes and Table 6, page 20, gives an
overview of the operating mode.

Notes:
WD - means Watchdog
WD disabled - means Watchdog disabled (WDCONF terminal connected to GND)
WD trigger – means Watchdog is triggered by SPI command
WD failed – means no Watchdog trigger or trigger occurs in closed window
STOP Command - means STOP command sent via SPI
SLEEP Command - means SLEEP command send via SPI
Wake-Up - means L1 or L2 state change or LIN bus wake up or SS rising edge
