These 64-bit registers are called low-priority mailbox registers (or low-priority mailboxes). When a value is written to the least
significant 32 bits of these registers, an event (known as a Mailbox Event) is generated to the RX RISC. Only lower 32 bits
of these 64-bit low-priority mailbox registers are implemented.
