6.13 SSP serial I/O controller
6.14 General purpose timers/external event counters
The LPC2131/32/34/36/38 each contain one Serial Synchronous Port controller (SSP).
The SSP controller is capable of operation on a SPI, 4-wire SSI, or Microwire bus. It can
interact with multiple masters and slaves on the bus. However, only a single master and a
single slave can communicate on the 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. Often only one of these data flows carries
meaningful data.
The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an
externally supplied clock, 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.
At any given time only one of peripheral’s capture inputs can be selected as an external
event signal source, i.e., timer’s clock. The rate of external events that can be
successfully counted is limited to PCLK/2. In this configuration, unused capture lines can
be selected as regular timer capture inputs.
