with a value of 0. READ/WRITE attributes, reset conditions, and bit descriptions of all
UART registers are provided in this section.
If less than eight bits are programmed for transmission, the lower bits of the byte written
to the UART Transmit Holding Register, listed in
The transmit FIFO is mapped at this address. You can write up to 16 bytes for transmission
at one time to this address if the FIFO is enabled by the application. If the FIFO is dis-
abled, this buffer is only one byte deep. These registers share the same address space as
the UARTx_RBR and BRGx_DLR_L registers.
The bits in this register reflect the data received. If less than eight bits are programmed for
the receive function, the lower bits of the byte reflect the bits received, whereas upper
unused bits are 0. The receive FIFO is mapped at this address. If the FIFO is disabled, this
buffer is only one byte deep.

as the UARTx_THR and BRGx_DLR_L registers.
