ACR

__IOM uint32_t LPC_UART3_Type::ACR

(@ 0x00000020) Auto-baud Control Register. Contains controls for the auto-baud feature.

DLL

__IOM uint32_t LPC_UART3_Type::DLL

(@ 0x00000000) Divisor Latch LSB. Least significant byte of the baud rate divisor value. The full divisor is used to generate a baud rate from the fractional rate divider (DLAB =1).

DLM

__IOM uint32_t LPC_UART3_Type::DLM

(@ 0x00000004) Divisor Latch MSB. Most significant byte of the baud rate divisor value. The full divisor is used to generate a baud rate from the fractional rate divider (DLAB =1).

FCR

__OM uint32_t LPC_UART3_Type::FCR

(@ 0x00000008) FIFO Control Register. Controls UART FIFO usage and modes.

FDR

__IOM uint32_t LPC_UART3_Type::FDR

(@ 0x00000028) Fractional Divider Register. Generates a clock input for the baud rate divider.

IER

__IOM uint32_t LPC_UART3_Type::IER

(@ 0x00000004) Interrupt Enable Register. Contains individual interrupt enable bits for the 7 potential UART interrupts (DLAB =0).

IIR

__IM uint32_t LPC_UART3_Type::IIR

(@ 0x00000008) Interrupt ID Register. Identifies which interrupt(s) are pending.

LCR

__IOM uint32_t LPC_UART3_Type::LCR

(@ 0x0000000C) Line Control Register. Contains controls for frame formatting and break generation.

LSR

__IM uint32_t LPC_UART3_Type::LSR

(@ 0x00000014) Line Status Register. Contains flags for transmit and receive status, including line errors.

RBR

__IM uint32_t LPC_UART3_Type::RBR

(@ 0x00000000) Receiver Buffer Register. Contains the next received character to be read (DLAB =0).

RESERVED

__IM uint32_t LPC_UART3_Type::RESERVED

RESERVED1

__IM uint32_t LPC_UART3_Type::RESERVED1

RESERVED2

__IM uint32_t LPC_UART3_Type::RESERVED2

RESERVED3

__IM uint32_t LPC_UART3_Type::RESERVED3

RESERVED4

__IM uint32_t LPC_UART3_Type::RESERVED4[6]

RS485ADRMATCH

__IOM uint32_t LPC_UART3_Type::RS485ADRMATCH

(@ 0x00000050) RS-485/EIA-485 address match. Contains the address match value for RS-485/EIA-485 mode.

RS485CTRL

__IOM uint32_t LPC_UART3_Type::RS485CTRL

(@ 0x0000004C) RS-485/EIA-485 Control. Contains controls to configure various aspects of RS-485/EIA-485 modes.

RS485DLY

__IOM uint32_t LPC_UART3_Type::RS485DLY

(@ 0x00000054) RS-485/EIA-485 direction control delay.

SCR

__IOM uint32_t LPC_UART3_Type::SCR

(@ 0x0000001C) Scratch Pad Register. 8-bit temporary storage for software.

TER

__IOM uint32_t LPC_UART3_Type::TER

(@ 0x00000030) Transmit Enable Register. Turns off UART transmitter for use with software flow control.

THR

__OM uint32_t LPC_UART3_Type::THR

(@ 0x00000000) Transmit Holding Regiter. The next character to be transmitted is written here (DLAB =0).
