摘要：
In an example, a system-on-chip (SoC) includes a hardware power-on-reset (POR) sequencer circuit coupled to a POR pin. The SoC further includes a platform management unit (PMU) circuit, coupled to the hardware POR sequencer circuit, the PMU including one or more central processing units (CPUs) and a read only memory (ROM). The SoC further includes one or more processing units configured to execute a boot process. The hardware POR sequencer circuit is configured to initialize the PMU. The one or more CPUs of the PMU are configured to execute code stored in the ROM to perform a pre-boot initialization.
