Description

Clock Input for Serial Port in SPI Mode.

Clock Mode. In pin mode, determines phase of internal retiming clock.

DCLKIO = CLKIN: Tie to 0.

DCLKIO ≠ CLKIN: Pulse 0 to 1 to edge trigger the internal retimer (see the Retimer section).

Bidirectional Data Line for Serial Port in SPI Mode.

Data Format. In pin mode, determines data format of digital data.

Active Low Chip Select in SPI Mode.

Power Down. In pin mode, powers down the device except for SPI port.
