Single-chip 32-bit microcontrollers

6.10 UARTs

The LPC2104, LPC2105 and LPC2106 each contain two UARTs. One UART

provides a full modem control handshake interface, the other provides only transmit

and receive data lines.

6.10.1 Features

• 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 UART 1.

6.11 I2C serial I/O controller

I2C is a bi-directional bus for inter-IC control using only two wires: a serial clock 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. I2C is a

multi-master bus, it can be controlled by more than one bus master connected to it.

I2C implemented in LPC2104, LPC2105 and LPC2106 supports bit rate up to

400 kbit/s (Fast I2C).

6.11.1 Features

• Standard I2C compliant bus interface.

• 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.

• The I2C bus may be used for test and diagnostic purposes.
