6.12.5.1 UART Control Registers Map

R: read only, W: write only, R/W: both read and write, C: Only value 0 can be written

UART_RBR 0x00

Receive Buffer Register (DLAB = 0) Undefined

UART_THR 0x00

Transmit Holding Register (DLAB = 0) Undefined

UART_IER 0x04

UART_MCR 0x10

R/W

Modem Control Register (Optional) 0x0000_0000

UART_LSR 0x14

R Line Status Register

0x6060_6060

UART_MSR 0x18

R MODEM Status Register (Optional)

0x0000_0000

UART_TOR 0x1C

R/W Time Out Register

0x0000_0000

Note: Real register address = 0xFFF8_0000+ (UART number – 1) * (0x0100) + offset

Note: All of these registers are implemented 8-bit in UART design and it will be repeated 4 times

before send to APB bus. For example, when ARM CPU read register UARTn_BRR, ARM CPU will get

UART0_RBR = {RBR[7:0], RBR[7:0], RBR[7:0], RBR[7:0]}.
