12.4. Reset Sequencing
The reset controller sequences resets without software assistance. Module reset signals are asserted asynchronously and synchronously. The reset manager deasserts the module reset signals synchronous to the boot_clk clock. Module reset signals are deasserted in groups in a fixed sequence. All module reset signals in a group are deasserted at the same time.
The reset manager sends a request to the clock manager to put the clocks in boot mode, which creates a fixed and known relationship between the boot_clk clock and all other clocks generated by the clock manager.
In secure mode, the source of boot_clk clock is an internal oscillator, while in non-secure mode, the source is HPS_OSC_CLK clock.
