31. Enhanced Serial Peripheral Interface with DMA Support (SPI1)
The Enhanced Serial Peripheral Interface (SPI1) provides access to a flexible, full-duplex synchronous
serial bus. SPI1 can operate as a master or slave device in both 3-wire or 4-wire modes, and supports
multiple masters and slaves on a single SPI bus. The slave-select (NSS) signal can be configured as an
input to select SPI1 in slave mode, or to disable Master Mode operation in a multi-master environment,
avoiding contention on the SPI bus when more than one master attempts simultaneous data transfers.
NSS can also be configured as a chip-select output in master mode, or disabled for 3-wire operation.
Additional general purpose port I/O pins can be used to select multiple slave devices in master mode.
