The 11/2016 T2080 Ref Manual shows Normal GPCM read operation for a burst in Figure 13-47. It appears to be incorrect however. The parameter in question is the TRAD delay shown from the falling edge of OE_SYNC to SAMP_PULSE. Is that really TRAD, or simply 2 clocks in length based on the discussion a couple of pages earlier. The delays between the SAMP_PULSE would then be TRAD based on the timing above it, but the first delay seems incorrect. I would assume that the T2080 is only going to cause 1 set of TRAD delays (could be 100 ns or longer) and not 2 sets as shown in the figure. It appears that OE_SYNC, DATA_SYNC and SAMP_PULSE signals are all internal to the T2080 and attempting to show the relationship between the external bus, the internal/external clocks and the data buses.
