Where is info on the OMAP-L138 "starvation interrupt" register?

For the OMAP-L138, where is info on the "starvation interrupt" register?  (I suspect it this interrupt occurs when the CPPI tries to read a buffer descriptor from the submit queues, when they are empty -- thus "starved".)

The Starterware software uses this register, and gives its USB-On-the-Go address as 0x3200.  But I can find no register at that address, and I can find no "starvation interrupt" in the Tech Ref Manual (spruh77a.pdf)

(Reference:  In Starterware, this usage occurs in the function "CppiDmaGetINTD0Status", in the file cppi41cma.c)
