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

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

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
