Definition:
UART Line Control Register Middle.
Bit Descriptions:
RSVD:
Reserved. Unknown During Read.
BR:
Baud Rate Divisor bits [15:8]. Most significant byte of baud
rate divisor. These bits are cleared to 0 on reset.

Address:
0x808D_0010 - Read/Write
Default:
0x0000_0000
Definition:
UART Line Control Register Low.
Bit Descriptions:
RSVD:
Reserved. Unknown During Read.
BR:
Baud Rate Divisor bits [7:0]. Least significant byte of baud
rate divisor. These bits are cleared to 0 on reset. The baud
rate divisor is calculated as follows:
Baud rate divisor BAUDDIV = (F
UARTCLK
/ (16 * Baud
rate)) –1
where F
UARTCLK
is the UART reference clock frequency. A
baud rate divisor of zero is not allowed and will result in no
data transfer.
