7.11 SSP/SPI serial I/O controller
The LPC122x contain one SSP/SPI controller. The SSP/SPI controller is capable of
operation on a SSP, 4-wire SSI, or Microwire bus. It can interact with multiple masters and
slaves on the bus. 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. In
practice, often only one of these data flows carries meaningful data.
The LPC122x contain one 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.
