Description
Type Reset
Reserved, write zero, read as don’t care
If set the first to Mini UART register give access the R/W 0
the Baudrate register. During operation this bit must
be cleared.
If set high the UART1_TX line is pulled low
R/W 0
continuously. If held for at least 12 bits times that will
indicate a break condition.
Reserved, write zero, read as don’t care
Some of these bits have functions in a 16550
0
compatible UART but are ignored here
If clear the UART works in 7-bit mode
If set the UART works in 8-bit mode
R/W 0
AUX_MU_MCR_REG Register (0x7E21 5050)

If clear the UART1_RTS line is high
If set the UART1_RTS line is low
This bit is ignored if the RTS is used for auto-flow
control. See the Mini Uart Extra Control register
