Set to 0. 10:8 PRI1 Secondary Priority Level. This value is the priority level the DC uses when performing high priority GLIU0 accesses. This is the case when the FIFOs are nearly empty. 7 RSVD Reserved. Set to 0. 6:4 PRI0 Primary Priority Level. This value is the priority level the DC uses for most accesses (i.e., when the display FIFO is not in danger of being emptied). 3 RSVD Reserved. Set to 0. 2:0 PID Priority ID. This value is the Priority ID (PID) value used when the DC initiates GLIU0 transactions.
