Memory Arbiter Status Register (offset: 0x4004)
Enable 1 RW 1 This bit controls whether the Memory Arbiter is
active or not. When set to 0, it completes the
current operation and cleanly halts. Until it is
completely halted, it remains 1 when read.
Reset 0 RW 0 When this bit is set to 1, the Memory Arbiter state
machine is reset. This is a self-clearing bit.
