12.1.2.1
This mode is entered from the reset mode whenever the SLIC module supply voltage V
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.
12.1.2.2
This mode is entered from the power off mode whenever the SLIC module supply voltage V
its minimum specified value (V
from 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., LVR, POR, COP, RST pin, etc.) is asserted. SLIC reset mode may also be entered by the user
software by asserting the INITREQ bit. INITACK indicates whether the SLIC module is in the reset mode
as a result of writing INITREQ in SLCC1. While in the reset state the SLIC module clocks are stopped.
Clearing the INITREQ allows the SLIC to proceed and enter SLIC run mode (if SLCE is set). The module
