Description

14

INT

O

Active Low output interrupt signal. Active when a SE0 is detected while in HNP

mode. This pin has an internal 220 k

Ω pull-down to ground when HIGHZ=”H” only.

15

PWR

Data line pull-up supply voltage. Connect an external 1.5 k

Ω resistor to D+ (full-

speed) or D- (low-speed). Pin output is controlled by SUSPEND, SPEED# and

SOFTCON inputs.

16

SOFTCON

I

Normally used as Software controlled enumeration pin: controls the status of VPU

pin and the connection of internal weak pull-up resistor. LOW: VPU floating

(SUSPEND=”0” or “1”). HIGH: VPU = 3.3 V. Functionality can change depending on

status of SPEED# and SUSPEND pins. See Table 12 for more details.
