The system error accumulator modules are programmed to generate one or more system signal activities.

  • PMC Error Status Registers
    • Generate PMC IRQ interrupt to PLM
    • Assert ERROR_OUT output pin (PIN)
    • Assert system reset (SRST)
    • Assert internal POR
    • Most error in the JTAG controller error register, listed in ERROR_STATUS Register
  • PSM Error Status Registers
    • General IRQ handler in PSM firmware
    • Correctable IRQ handler in PSM firmware
    • Uncorrectable IRQ handler in PSM firmware
  • System error signals are also routed to the PL

After the system error is latched, they are routed so they can generate one or more actions.
