908E622 ANALOG DIE MODES OF OPERATION
The 908E622 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.
The different modes can be selected by the STOP and
SLEEP bits in the System Control Register.
Figure 11 describes how transitions are done between the
different operating modes, and Table 6, page 27 gives an
overview of the operating modes.
Figure 11. Operating Modes and Transitions
Normal Mode
This Mode is normal operating mode of the device. All
functions and power stages are active and can be enabled/
disabled. The voltage regulator provides the +5V VDD to the
MCU.
After a reset (e.g. Power On Reset, Wake-Up from Sleep),
the MCU sets the PSON bit in the System Control Register
within 80ms typical (tNORMREQ). This is to ensure the MCU
has started up and is operating correctly. If the PSON bit is
not set within the required time frame, the device enters
SLEEP mode to reduce power consumption (fail safe).
This MCU monitoring can be disabled, e.g. for
programming by applying VDD on the TESTMODE pin.
Stop Mode
In Stop mode, the voltage regulator still supplies the MCU
with VDD (limited current capability). To enter the Stop mode,
the STOP bit in the System Control Register has to be set
and the MCU has to be stopped (see the 908EY16 datasheet
for details).
Wake-up from this mode is possible by LIN bus activity or
the wake-up input L0, and is maskable with the LINIE and/or
L0IE bits in the Interrupt Mask Register. The analog die is
generating an interrupt on IRQ_A pin to wake-up the MCU.
The wake-up / interrupt source can be evaluated with the
L0IF and LINIF bits in the Interrupt Flag Register.
Stop mode has a higher current consumption than Sleep
mode, but allows a quicker wake-up. Additionally, the wake-
