Description
Reset in SPI Mode. Pulse high to reset SPI registers to default values.
Pin Mode. A constant Logic 1 puts device into pin mode.
Serial Clock. Clock input for serial port in spi mode.
Clock Mode. In pin mode, CLKMD 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).
Serial Port Input/Output. Bidirectional data line for serial port in spi mode.
Data Format. In pin mode, FORMAT determines data format of digital data.
Chip Select. Active low chip select in spi mode.
Power Down. In pin mode, PWRDN powers down the device except for the SPI port.
Digital Input (MSB).
Digital Input.
The heat sink pad is connected to AVSS and should be soldered to the ground plane. Exposed metal at
package corners is connected to this pad.
