UARTE - Delay from STOPRX to ENDRX Interrupt

Hi there,

I'm attempting to use the UARTE for a continuous read scenario but I am noticing there is significant delay between the STOPRX task and the ENDRX interrupt (~5.6ms when at 9500 baud).

Figure 95 of the product specification (page 332) shows the ENDRX will occur within a byte. It's almost as if the ENDRX is happening when RXTO occurs...

What is the source of this delay?

Here is an oscilloscope capture, you can see STOPRX is triggered during a small idle time, and ENDRX has a delay:
