There are Kick and Proxy registers associated with each CTRL_MMR partition. This section describes the Proxy registers. For information about the Kick registers see Section 5.1.2.3.
The Proxy registers provide proxy addressing, allowing each of the CTRL_MMR registers to be accessed through two different addresses - Proxy0 and Proxy1. Each partition is 16KB. The first 8KB are for Proxy0 addresses, and the second 8KB are for Proxy1 addresses. The Proxy0 address is intended as the normal read and write access address. The Proxy1 address provides exclusive register write control.
When a bit from the Px_CLAIMy[31-0] PROXY1_CLAIMED field is set to 1h, a register becomes read-only at its Proxy0 address and may only be written through its Proxy1 address. The Proxy registers themselves may always be read through their Proxy0 address but may only be written through their Proxy1 address.
The x (representing the partition) and y indices can be calculated through the following equations:
