Description
0:7
WODe
Bits to control open drain emulation for individual WakeUp GPIO configured as outputs.
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 = Normal CMOS output (default).
1 = Open Drain emulation (a drive to high creates Hi-Z).
