Table 54. UART Transmit Holding Registers(UART0_THR = 00C0h, UART1_THR =
UART Receive Buffer Register
The bits in this register reflect the data received. If less than eight bits are programmed for
receive, 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.
These registers share the same address space as the UARTx_THR and UARTx_BRG_L
registers. See
Table 55. UART Receive Buffer Registers(UART0_RBR = 00C0h, UART1_RBR =
00 D0h)
