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
controlled by more than one bus master connected to it.

The LPC2212/2214 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.

C-bus serial I/O controller
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.
The I
Compliant with Serial Peripheral Interface (SPI) specification.
Synchronous, Serial, Full Duplex communication.
Combined SPI master and slave.
Maximum data bit rate of
Eight to 16 bits per frame.
