23.3.2.3 Results Register

RR is the Results Register. This Read Only register is a 16-entry × 16-bit wide FIFO that
holds 10-bit ADC output and the 4-bit tag number from the Control Bank State Machine.
The read-and-write pointer specifies the FIFO entry to access when a Read or Write is
requested. When the FIFO is full, further data writes are temporarily blocked until at least
one location is available for the write. Reading from RR removes an entry from the First
Out end of the result FIFO.
