Chapter 17 Crossbar Switch (AXBS)
Parking may continue to be used in a round-robin mode, but does not affect the round-
robin pointer unless the parked master actually performs a transfer. Handoff occurs to the
next master in line after one cycle of arbitration. If the slave port is put into low-power
park mode, the round-robin pointer is reset to point at master port 0, giving it the highest
priority.
17.3.3.4 Priority assignment
Each master port needs to be assigned a unique 3-bit priority level. If an attempt is made
to program multiple master ports with the same priority level within the priority registers
(PRSn), the crossbar switch responds with a bus error and the registers are not updated.
17.4 Initialization/application information
No initialization is required by or for the crossbar switch. Hardware reset ensures all the
register bits used by the crossbar switch are properly initialized to a valid state. Settings
and priorities should be programmed to achieve maximum system performance.
