GLD_MSR_CONFIG Bit Descriptions
Bit Name Description
63:11 RSVD Reserved. 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.
