3.7

SPI - Chip Select Pin (CS)

The CS pin enables/disables the serial interface (SDI,

SDO, and SCK). The serial interface must be enabled

for the device to receive any serial commands.

Refer to Section 6.4 “Interface Pins (CS, SCK, SDI,

SDO, and LAT/HVC)” for more details regarding the

SPI serial interface communication.

3.8

SPI - Serial Clock Pin (SCK)

The SCK pin is the serial clock pin of the SPI interface.

The MCP48CXBXX SPI Interface only accepts external

serial clocks.

3.9

SPI - Serial Data In Pin (SDI)

The SDI pin is the serial data input pin of the SPI

interface. The SDI pin is used to write the DAC wiper

registers and configuration bits.

3.10

SPI - Serial Data Out Pin (SDO)

The SDO pin is the serial data output pin of the SPI

interface. The SDO pin is used to read the DAC wiper

registers and configuration bits.
