Receiver Buffer Register (RBR)
The ACE receiver section consists of a receiver shift register (RSR) and a RBR. The RBR is actually a 16-byte
FIFO. Timing is derived from the input clock divided by the programmed devisor. Receiver section control is a
function of the ACE line control register.
Scratch Register
The scratch register is an 8-bit register that is intended for the programmer's use as a scratchpad in the sense
that it temporarily holds the programmer's data without affecting any other ACE operation.

The ACE RSR receives serial data from RX. The RSR then concatenates the data and moves it into the RBR
FIFO. In the TL16C450 mode, when a character is placed in the RBR and the received data available interrupt is
enabled (IER0 = 1), an interrupt is generated. This interrupt is cleared when the data is read out of the RBR. In
the FIFO mode, the interrupts are generated based on the control setup in the FIFO control register.
