Message

Message Processing

Power Management PM_PME, PME_TO_Ack

The Application Layer transmits the PM_PME request via the apps_pm_xmt_pme input.

The Application Layer transmits the apps_ready_entr_l23 to indicate that it is ready to enter the L23 state.

Vendor Defined with or without Data Vendor_Type0 The Application Layer must generate and transmit this on the Avalon®-ST TX interface.
ATS ATS_Request, ATS_Invalidate Completion The Application Layer must generate and transmit these Messages on the Avalon®-ST TX interface.
INT INTx_Assert, INTx_Deassert The Application Layer transmits the INTx_Assert and INTx_Deassert Messages using the app_int interface.
ERR ERR_COR, ERR_NONFATAL, ERR_FATAL The IP core transmits these error Messages autonomously when it detects internal errors. It also receives and forwards these errors when received from the Application Layer via the app_err_* interface.
