Description

Pin configuration register for pins USB1_DM and USB1_DP

Fields

USB_AIM

Differential data input AIP/AIM.

0 (GOING_LOW_WITH_FULL): Going LOW with full speed edge rate

1 (GOING_HIGH_WITH_FULL): Going HIGH with full speed edge rate

USB_ESEA

Control signal for differential input or single input.

0 (RESERVED): Reserved. Do not use.

1 (SINGLE_INPUT): Single input. Enables USB1. Use with the on-chip full-speed PHY.

USB_EPD

Enable pull-down connect.

0 (PULL_DOWN_DISCONNECT): Pull-down disconnected

1 (PULL_DOWN_CONNECTED): Pull-down connected

RESERVED

Reserved

USB_EPWR

Power mode.

0 (POWER_SAVING_MODE_S): Power saving mode (Suspend mode)

1 (NORMAL_MODE): Normal mode

USB_VBUS

Enable the vbus_valid signal. This signal is monitored by the USB1 block. Use this bit for software de-bouncing of the VBUS sense signal or to indicate the VBUS state to the USB1 controller when the VBUS signal is present but the USB1_VBUS function is not connected in the SFSP2_5 register. The setting of this bit has no effect if the USB1_VBUS function of pin P2_5 is enabled through the SFSP2_5 register.

0 (VBUS_SIGNAL_LOW_OR_I): VBUS signal LOW or inactive

1 (VBUS_SIGNAL_HIGH_OR): VBUS signal HIGH or active
