Description
0:7
WDDR[7:0]
Individual bits to control directionality of the pin as GPIO.
Bit 0 controls GPIO_WKUP_7 (GPIO_WKUP_7 pin)
Bit 1 controls GPIO_WKUP_6 (GPIO_WKUP_6 pin)
Bit 2 controls GPIO_WKUP_5 (PSC6_1 pin)
Bit 3 controls GPIO_WKUP_4 (PSC6_0 pin)
Bit 4 controls GPIO_WKUP_3 (ETH_17 pin)
Bit 5 controls GPIO_WKUP_2 (PSC3_9 pin)
Bit 6 controls GPIO_WKUP_1 (PSC2_4 pin)
Bit 7 controls GPIO_WKUP_0 (PSC1_4 pin)
0 = Pin is Input (default).
1 = Pin is Output.

WDVO
Individual bits to control the state of pins configured as GPIO output.
Bit 0 controls GPIO_WKUP_7 (GPIO_WKUP_7 pin)
Bit 1 controls GPIO_WKUP_6 (GPIO_WKUP_6 pin)
Bit 2 controls GPIO_WKUP_5 (PSC6_1 pin)
Bit 3 controls GPIO_WKUP_4 (PSC6_0 pin)
Bit 4 controls GPIO_WKUP_3 (ETH_17 pin)
Bit 5 controls GPIO_WKUP_2 (PSC3_9 pin)
Bit 6 controls GPIO_WKUP_1 (PSC2_4 pin)
Bit 7 controls GPIO_WKUP_0 (PSC1_4 pin)
0 = Drive 0 on the pin (default).
1 = Drive 1 on the pin.
Note: If pin is emulating open drain, this setting results in Hi-Z
