I
The LPC2194 contains 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.
The Timer is designed to count cycles of the peripheral clock (PCLK) and optionally
generate interrupts or perform other actions at specified timer values, based on four
match registers. It also includes four capture inputs to trap the timer value when an
input signal transitions, optionally generating an interrupt. Multiple pins can be
selected to perform a single capture or match function, providing an application with
‘or’ and ‘and’, as well as ‘broadcast’ functions among them.

C implemented in LPC2194 supports bit rate up to 400 kbit/s (Fast I
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 one eighth of the input clock rate.
A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
