Table 7. Table of Operations
APPLICATION WAKE-UP FROM THE 33742
from the SBC side. When a wake-up condition is detected by
the SBC (for example, CAN, wake-up input), the 33742
enters the Normal Request mode and generates an interrupt
pulse at the INT pin.
APPLICATION WAKE-UP FROM THE MCU
may come from the system MCU. In this case the MCU
selects the device the using a LOW-to-HIGH transition on the
33742 CS pin. Then the 33742S goes into Normal Request
mode and generates an interrupt pulse at the INT pin.
