6.12 UARTs
The LPC2114/LPC2124 each contain two UARTs. One UART provides a full modem
control handshake interface, the other provides only transmit and receive data lines.
6.12.1
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 UART1.
6.13 I
2
C serial I/O controller
I
2
C 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. I
2
C is a
multi-master bus, it can be controlled by more than one bus master connected to it.
I
2
C implemented in LPC2114/LPC2124 supports bit rate up to 400 kbit/s (Fast I
2
C).
6.13.1
Features
Standard I
2
C 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 I
2
C bus may be used for test and diagnostic purposes.
6.14 SPI serial I/O controller
The LPC2114/LPC2124 each contain two SPIs. The SPI is a full duplex serial
interface, designed to be able to handle multiple masters and slaves connected to a
given bus. Only a single master and a single slave can communicate on the interface
during a given data transfer. During a data transfer the master always sends a byte of
data to the slave, and the slave always sends a byte of data to the master.
