bus during a given data transfer. The SSP supports full duplex transfers, with frames of
4 bits to 16 bits of data flowing from the master to the slave and from the slave to the
master. In practice, often only one of these data flows carries meaningful data.
The LPC1759/58/56/54/52/51 each contain two I
The I
(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.

C-bus serial I/O controllers
S-bus serial I/O controllers (LPC1759/58/56 only)
Maximum SSP speed of 50 Mbit/s (master) or 8 Mbit/s (slave)
Compatible with Motorola SPI, 4-wire Texas Instruments SSI, and National
Semiconductor Microwire buses
Synchronous serial communication
Master or slave operation
8-frame FIFOs for both transmit and receive
4-bit to 16-bit frame

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.
