Part Number:AM5728
Tool/software: TI-RTOS
Hello, TI Experts,
Our customer sent us questions about "INTA function" of PCIE by using PROCESSOR-SDK-RTOS-AM57X.
They are using AM5728 as EP(Endpoint) for their product which is connected to Windows-PC via PCIE-slot.
They try to realize "Assert INTA" and "Deassert INTA" function to design their software.
So, they understand how to realize "INTA function" by using below registers.
SPRUHZ6K.pdf : "24.9.4.6.2.1.2 Legacy PCI Interrupt Transmission (EP mode only)"
But they need to reduce the delay from PC to negate INTA.
(Please refer attached pdf in detail.)
Question:
Could tell us how to reduce this delay from PC to negate INTA?
- Are there any special pin to set the deassert INT register without software interrupt handling?
If there are any recommended way or successful implementation for faster negating INTA by AM572x, please tell us.
Best regards,
