4.1.3. Module Reset Signals
The following tables list the module reset signals. The module reset signals are organized in groups for the MPU, peripherals, bridges.
In the following tables, columns marked for Cold Reset, Warm Reset, and Debug Reset denote reset signals asserted by each type of reset. For example, writing a 1 to the swwarmrstreq bit in the ctrl register resets all the modules that have a checkmark in the Warm Reset column.
The column marked for Software Deassert denotes reset signals that are left asserted by the reset manager.
