Read only
Reserved bits: always read zero.
Read/Write
Self-clearing on clock after write.
Read with Reset on Write. Writing a 1 resets corresponding bit location. Writing 0 has no effect.
Internal Synchronized Write. Same as RW, but internal source can also write to register upon asserting a write
strobe. This write must be synchronized to local clock domain.
Pulse on Write. Same as RW, but detecting a write (byte granularity) generates a one-clock pulse.
Pulse on Read. Same as RW, but detecting a read (byte granularity) generates a one-clock pulse.
