P89LPC952/954
8-bit microcontroller with 10-bit ADC
7.21 SPI
The P89LPC952/954 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 either
Master or 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 ows from master to slave on MOSI (Master Out Slave In) pin and ows
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 congured for port functions.
SS is the optional slave select pin. In a typical conguration, 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.
Typical connections are shown in Figure 12 through Figure 14.
