7.22 Serial Peripheral Interface (SPI)
The P89LPC932A1 provides another high-speed serial communication interface—the SPI
interface. SPI is a full-duplex, high-speed, synchronous communication bus with two
operation modes: Master mode and Slave mode. Up to 3 Mbit/s can be supported in
Master mode or up to 2 Mbit/s in Slave mode. It has a Transfer Completion Flag and Write
Collision Flag Protection.
The SPI interface has four pins: SPICLK, MOSI, MISO and SS:

SPICLK, MOSI and MISO are typically tied together between two or more SPI
devices. Data flows from master to slave on MOSI (Master Out Slave In) pin and flows
from slave to master on MISO (Master In Slave Out) pin. The SPICLK signal is output
in the master mode and is input in the slave mode. If the SPI system is disabled, i.e.,
SPEN (SPCTL.6) = 0 (reset value), these pins are configured for port functions.
SS is the optional slave select pin. In a typical configuration, an SPI master asserts
one of its port pins to select one SPI device as the current slave. An SPI slave device
uses its SS pin to determine whether it is selected.
