6.13.1 Features
6.12 UARTs
6.13 I
The LPC2210/2220 contains two UARTs. One UART provides a full modem control
handshake interface, the other provides only transmit and receive data lines.
The I
line (SCL), and a serial data line (SDA). Each device is recognized by a unique address
and can operate as either a receiver-only device (e.g., an LCD driver or a transmitter with
the capability to both receive and send information (such as memory)). Transmitters
and/or receivers can operate in either master or slave mode, depending on whether the
chip has to initiate a data transfer or is only addressed. The I
it can be controlled by more than one bus master connected to it.

C-bus serial I/O controller
16 byte Receive and Transmit FIFOs.
Register locations conform to ‘550’ industry standard.
Receiver FIFO trigger points at 1, 4, 8, and 14 bytes
Built-in baud rate generator.
Standard modem interface signals included on UART1.
LPC2220 provides enhanced UARTs with fractional baud-rate generators,
mechanism for software flow control, and hardware (CTS/RTS) flow control on UART1
only.
Compliant with standard I
Easy to configure as Master, Slave, or Master/Slave.
Programmable clocks allow versatile rate control.
Bidirectional data transfer between masters and slaves.
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
