3.4.5.1

Configuration 1 - Mixed Mode

When the CFG_STRAP is configured to this mode, the programmable function pins (PROG_FUNC[7:1]) are set to pro-

vide an SMBus/I2C interface, 3 GPIOs, and FlexConnect capabilities. Table 3-16 details the PROG_FUNC[7:1] pin

assignments in this mode.

SMBus/I2C Data

The SMBus/I2C interface acts as SMBus slave or I2C bridge

dependent on the device configuration. Refer to Section 3.4.1,

"SPI/SMBus/I2C/UART Configuration (I2C_SLV_CFG[1:0])".

PROG_FUNC5

SMCLK

OD12

SMBus/I2C Clock

The SMBus/I2C interface acts as SMBus slave or I2C bridge

dependent on the device configuration. Refer to Section 3.4.1,

"SPI/SMBus/I2C/UART Configuration (I2C_SLV_CFG[1:0])".

PROG_FUNC6

FLEXCMD

FlexConnect Control

0: Normal Operation (Port 0 upstream, Port 1 downstream)

1: Flex Operation (Port 1 upstream, Port 0 downstream)

Note:

Refer to Section 8.2, "FlexConnect" for additional

information.

PROG_FUNC7

USB2_SUSP_IND

O10

USB2.0 Suspend Indicator

USB2_SUSP_IND can be used as a sideband remote wakeup

signal for the host when in USB2.0 suspend.

Note:

Refer to Section 8.5, "Remote Wakeup Indicator"

for additional information.
