Devices communicate in master/slave mode with 4-wire bi-direction interface. The NuMicro ™ NUC100/NUC120 Medium Density contains up to four sets of SPI controller performing a serial-to-parallel conversion on data received from a peripheral device, and a parallel-to-serial conversion on data transmitted to a peripheral device. Each set of SPI controller can be set as a master that can drive up to 2 external peripheral slave devices; it also can be configured as a slave device controlled by an off-chip master device. NuMicro ™ NUC100/NUC120 Low D This controller supports a variable serial clock for special application and it also supports 2-bit transfer mode to connect 2 off-chip slave devices at the same time. The SPI controller also supports PDMA function to access the data buffer. 2 Features Up to four sets of SPI controller for NuMicro ™ NUC100/NUC120 Medium D Support mas Support 1-bit or 2-bit transfer mode Configurable bit length up to 32-bit of a transfer word and configu of a transaction, so the maximum bit length is 64-bit for e Provide burst mode operation, transm transaction in one transfer Support MSB or LSB f 2 device/slave select lines in master mo Support byte reorder function Support byte or word suspend mode Variable output serial Support two programmable serial clock frequencies Support two channel PDMA request, one for tra |
