Read only
Forces the slave port’s CSRn and PRSn registers to be read-only. After set, only a hardware reset clears
it.

Halt low priority
Sets the initial arbitration priority for low power mode requests. Setting this bit will not effect the request
for low power mode from attaining highest priority once it has control of the slave ports.

Parking control
Determines the slave port’s parking control. The low-power park feature results in an overall power
savings if the slave port is not saturated. However, this forces an extra latency clock when any master
tries to access the slave port while not in use because it is not parked on any master.

Park
Determines which master port the current slave port parks on when no masters are actively making
requests and the PCTL bits are cleared.

The slave port’s registers are writeable
The slave port’s registers are read-only and cannot be written. Attempted writes have no effect on the
registers and result in a bus error response.
The low power mode request has the highest priority for arbitration on this slave port
The low power mode request has the lowest initial priority for arbitration on this slave port

When no master makes a request, the arbiter parks the slave port on the master port defined by the
PARK bit field
When no master makes a request, the arbiter parks the slave port on the last master to be in control
of the slave port
When no master makes a request, the slave port is not parked on a master and the arbiter drives all
