Pin No.

Mnemonic

Description

F12

Serial Port Chip Select Bar (Active Low) Input.

CMOS levels on this pin are determined with

respect to IOVDD.

TX_ENABLE

Transmit Enable Input. This pin can be used

instead of the DAC output bias power down bits

in Register 0x040, Bits [1:0] to enable the DAC

output. CMOS levels are determined with

respect to IOVDD.

IRQ

Interrupt Request Output (Active Low, Open

Drain).

G10

SDIO

Serial Port Data Input/Output. CMOS levels on

this pin are determined with respect to IOVDD.

G11

SDO

Serial Port Data Output. CMOS levels on this pin

are determined with respect to IOVDD.

H10

SCLK

Serial Port Data Clock. CMOS levels on this pin

are determined with respect to IOVDD.
