VPRBUSPRI

Arbitration priority on bus

Setting high priority will give VPR maximum priority and can cause starvation for other bus masters trying to access the same memory. It should only be used in limited sections of code and care must be taken to avoid continuous memory accesses to ensure other bus masters can perform interleaved accesses.

LowPriority

0x0

Low priority for VPR RAM transactions on bus
