Embedded Characteristics



Communication with Serial External Devices Supported

Master mode can drive SPCK up to peripheral clock

Slave mode operates on SPCK, asynchronously with core and bus clock

Four chip selects with external decoder support allow communication with up to 15peripherals

Serial memories, such as DataFlash and 3-wire EEPROMs

Serial peripherals, such as ADCs, DACs, LCD controllers, CAN controllers and sensors

External coprocessors



Master or Slave Serial Peripheral Bus Interface

8-bit to 16-bit programmable data length per chip select

Programmable phase and polarity per chip select

Programmable transfer delay between consecutive transfers and delay before SPI clock per chip

select
