6.7 Serial Peripheral Interface (SPI) Controller
NuMicro M051
The Serial Peripheral Interface (SPI) is a synchronous serial data communication protocol which
operates in full duplex mode. Devices communicate in master/slave mode with 4-wire bi-direction
interface. NuMicro M051
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; it
also can be configured as a slave device controlled by an off-chip master device.
Overview
Features
Up to two sets of SPI controller
Support master or slave mode operation
Configurable bit length up to 32 bits of a transfer word and configurable word numbers up to 2
Provide burst mode operation, transmit/receive can be transferred up to two times word
Support MSB or LSB first transfer
Byte or word Suspend Mode
Variable output serial clock frequency in master mode
Support two programmable serial clock frequencies in master mode
of a transaction, so the maximum bit length is 64 bits for each data transfer
transaction in one transfer
