Slave LIN Interface Controller (SLIC) Module
14.4 Interrupts
The SLIC module contains one interrupt vector, which can be triggered by sources encoded in the SLIC
state vector register. See
14.5 Modes of Operation
Figure 14-3
14.5.1 Power Off
This mode is entered from the reset mode whenever the SLIC module supply voltage V
its minimum specified value for the SLIC module to guarantee operation. The SLIC module will be placed
in the reset mode by a system low-voltage reset (LVR) before being powered down. In this mode, the pin
input and output specifications are not guaranteed.
14.5.2 Reset
This mode is entered from the power off mode whenever the SLIC module supply voltage V
its minimum specified value (V
entering an unknown state, the internal MCU reset is asserted while powering up the SLIC module. SLIC
reset mode is also entered from any other mode as soon as one of the MCU's possible reset sources (e.g.,
