IRDA

Individual bits to control the state of pins configured as GPIO output.

bit 2 controls GPIO_IRDA_1 (IR_USB_CLK pin)

bit 3 controls GPIO_IRDA_0 (IRDA_TX pin)

0 = Drive 0 on the pin (default)

1 = Drive 1 on the pin

4:7

ETHR

Individual bits to control the state of pins configured as GPIO output.

bit 4 controls GPIO_ETHI_3 (ETH_11 pin)

bit 5 controls GPIO_ETHI_2 (ETH_10 pin)

bit 6 controls GPIO_ETHI_1 (ETH_9 pin)

bit 7 controls GPIO_ETHI_0 (ETH_8 pin)

0 = Drive 0 on the pin (default)

1 = Drive 1 on the pin

8:11

Reserved

12:15

USB

Individual bits to control the state of pins configured as GPIO output.

bit 12 controls GPIO_USB_3 (USB1_8 pin)

bit 13 controls GPIO_USB_2 (USB1_7 pin)

bit 14 controls GPIO_USB_1 (USB1_6 pin)

bit 15 controls GPIO_USB_0 (USB1_0 pin)

0 = Drive 0 on the pin (default)

1 = Drive 1 on the pin

16:17

Reserved

18:23

PSC3

Individual bits to control the state of pins configured as GPIO output.

bit 18 controls GPIO_ PSC3_5 (PSC3_7 pin)

bit 19 controls GPIO_ PSC3_4 (PSC3_6 pin)

bit 20 controls GPIO_ PSC3_3 (PSC3_3 pin)

bit 21 controls GPIO_ PSC3_2 (PSC3_2 pin)

bit 22 controls GPIO_ PSC3_1 (PSC3_1 pin)

bit 23 controls GPIO_ PSC3_0 (PSC3_0 pin)

0 = Drive 0 on the pin (default)

1 = Drive 1 on the pin
