UnLSR0 is set when the UnRBR holds an unread character
and is cleared when the UARTn RBR FIFO is empty.
UnRBR is empty.
UnRBR contains valid data.
The overrun error condition is set as soon as it occurs. An
UnLSR read clears UnLSR1. UnLSR1 is set when UARTn
RSR has a new character assembled and the UARTn RBR
FIFO is full. In this case, the UARTn RBR FIFO will not be
overwritten and the character in the UARTn RSR will be lost.
Overrun error status is inactive.
Overrun error status is active.

1 stop bit.
2 stop bits (1.5 if UnLCR[1:0]=00).
Disable parity generation and checking.
Enable parity generation and checking.
Odd parity. Number of 1s in the transmitted character and
the attached parity bit will be odd.
Even Parity. Number of 1s in the transmitted character and
the attached parity bit will be even.
Forced "1" stick parity.
Forced "0" stick parity.
Disable break transmission.
Enable break transmission. Output pin UART0 TXD is
forced to logic 0 when UnLCR[6] is active high.
Disable access to Divisor Latches.
Enable access to Divisor Latches.
