C0_RX_STAT vs RX_INTSTAT_MASKED

Hi Cheng,

Which TRM? Which processor? Please be more specific.

Hi, Biser

The processor is AM335x.

TRM info: 

Literature Number: SPRUH73I

This is an old TRM. Latest revision is J. Page numbers that you gave do not match.

Hi, Biser

In TRM version J, p.1664 -> Read the RX_STAT register to determine which channel(s) caused the interrupt. As my understanding, the RX_STAT refers C0_RX_STAT. but in CE BSP (ti provided), interrupt handler read interrupt info from RX_INTSTAT_MASKED instead.

Are you referring to WinCE? This is third-party software (from Adeneo Embedded) and there is a dedicated forum for it: http://e2e.ti.com/support/embedded/wince/f/353.aspx

Hi, Biser

Forget windows CE. General speaking, in cpsw3g interrupt routine, which registers contain the info of DMA channel which cause the interrupt? C0_RX_STAT or RX_INTSTAT_MASKED?
