The Receive Holding Register is an 8-bit register that holds a receive data byte from the Receive Shift Register.
It provides the receive data interface to the host processor. The RHR register is part of the receive FIFO of 16
bytes by 11-bits wide, the 3 extra bits are for the 3 error tags to be reported in LSR register. When the FIFO is
enabled by FCR bit-0, the RHR contains the first data character received by the FIFO. After the RHR is read,
the next character byte is loaded into the RHR and the errors associated with the current data byte are
immediately updated in the LSR bits 2-4.

RHR Interrupt (ISR bit-2) programmed for
desired FIFO trigger level.
FIFO is Enabled by FCR bit-0=1
RTS# de-asserts when data fills above the flow
control trigger level to suspend remote transmitter.
Enable by EFR bit-6=1, MCR bit-2.
RTS# re-asserts when data falls below the flow
control trigger level to restart remote transmitter.
Enable by EFR bit-6=1, MCR bit-2.
