SERCOM SPI includes the following features:
- Full-duplex, four-wire interface (MISO,
MOSI, SCK, SS)
- One-level transmit buffer, two-level
or four-level receive
buffer
- Supports all four SPI modes of
operation
- Single data direction operation allows
alternate function on MISO or MOSI pin
- Selectable LSB- or MSB-first data
transfer
- Can be used with DMA
- Host operation:
- Serial clock speed,
fSCK=1/tSCK(1)
- 8-bit
clock generator
- Hardware
controlled SS
- 1.For tSCK and tSSCK
values, refer to SPI Timing Characteristics.
