FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
In order to select and activate the cyclic sense wake-up from the L0:L3 inputs, the WUR register must be configured with the
appropriate level sensitivity and the LPC register must be configured with 1xx1 data (bit LX2HS set at 1 and bit HSAUTO set
at 1. The wake-up mode selection (direct or cyclic sense) is valid for all four wake-up inputs.
FORCED WAKE-UP
The SBC can wake-up automatically after a predetermined time spent in Sleep or Stop mode. Cyclic Sense and Forced Wake-
up are exclusive. If Forced Wake-up is enabled (FWU bit set to 1 in the LPC register), Cyclic Sense cannot be enabled.
CAN INTERFACE WAKE-UP
The SBC incorporates a high-speed 1.0 Mbps CAN physical interface. It is compatible with ISO 11898-2 standard. The
operation of the CAN physical interface is controlled through the SPI. The CAN operating modes are independent of the 33742
operational modes.
The SBC can wake up from a CAN message if the CAN wake-up feature is enabled. Refer to the section titled LOGIC
COMMANDS AND REGISTERS beginning on page 46 for details of the wake-up detection.
SPI WAKE-UP
The 33742 can be awakened by changes on the CS pin in Sleep or Stop modes. Wake-up is detected as a LOW-to-HIGH level
transition on the CS pin. In the Stop mode, this corresponds to a condition where an MCU and the SBC are both in the Stop mode
and when the application wake-up event comes through the MCU.
33742 POWER-UP AND WAKE-UP FROM SLEEP MODE
After device or system power-up, or after the SBC awakens from Sleep mode, the 33742S enters into the Reset mode prior
to moving into Normal Request mode.
Figure 13, shows the device state diagram. Figure 14, shows device operation after power-up.
