LPC2917/01; LPC2919/01
ARM9 microcontroller with CAN and LIN
6.12.4
UARTs
The LPC2917/2919/01 contains two identical UARTs located at different peripheral base
addresses. The key features are:
16-byte receive and transmit FIFOs.
Register locations conform to 550 industry standard.
Receiver FIFO trigger points at 1 byte, 4 bytes, 8 bytes and 14 bytes.
Built-in baud rate generator.
Support for RS-485/9-bit mode allows both software address detection and automatic
address detection using 9-bit mode.
The UART is commonly used to implement a serial interface such as RS232. The
LPC2917/2919/01 contains two industry-standard 550 UARTs with 16-byte transmit and
receive FIFOs, but they can also be put into 450 mode without FIFOs.
6.12.4.1
Pin description
The UART pins are combined with other functions on the port pins of the
LPC2917/2919/01.
Table 16
shows the UART pins (x runs from 0 to 1).

Symbol
UARTx TXD
UARTx RXD
6.12.4.2
Clock description
The UART modules are clocked by two different clocks; CLK_SYS_PESS and
CLK_UARTx (x = 0-1), see
Section 6.7.2
. Note that each UART has its own CLK_UARTx
branch clock for power management. The frequency of all CLK_UARTx clocks is identical
since they are derived from the same base clock BASE_CLK_UART. The register
interface towards the system bus is clocked by CLK_SYS_PESS. The baud generator is
clocked by the CLK_UARTx.
6.12.5
Serial peripheral interface (SPI)
The LPC2917/2919/01 contains three Serial Peripheral Interface modules (SPIs) to allow
synchronous serial communication with slave or master peripherals.
The key features are:
Master or slave operation
Each SPI supports up to four slaves in sequential multi-slave operation
Supports timer-triggered operation
Programmable clock bit rate and prescale based on SPI source clock
(BASE_SPI_CLK), independent of system clock
Separate transmit and receive FIFO memory buffers; 16 bits wide, 32 locations deep
Programmable choice of interface operation: Motorola SPI or Texas Instruments
Synchronous Serial Interfaces
Programmable data-frame size from 4 to 16 bits
