4.5.2 Reset

The Reset Architecture of AM62A Low Power SK EVM is shown below. The SOC has the following resets:

  • RESETSTATz is the Main domain warm reset status output
  • PORz_OUT is the Main domain power ON reset status output
  • RESET_REQz is the Main domain warm reset input
  • MCU_PORz is the MCU domain power ON/ Cold Reset input
  • MCU_RESETSTATz is the MCU domain warm reset status output
Upon Power on Reset, all peripheral devices connected to the main domain get reset by RESETSTATz.
