Istat
Interrupt status bits for GPIO WakeUp pins 7–0.
1 indicates an interrupt occurred. Cleared with a sticky-bit write to a 1 to clear the interrupt
condition.
condition.
Bit 0 reflects interrupt on GPIO_WKUP_7 (GPIO_WKUP_7 pin)
Bit 1 reflects interrupt on GPIO_WKUP_6 (GPIO_WKUP_6 pin)
Bit 2 reflects interrupt on GPIO_WKUP_5 (PSC6_1 pin)
Bit 3 reflects interrupt on GPIO_WKUP_4 (PSC6_0 pin)
Bit 4 reflects interrupt on GPIO_WKUP_3 (ETH_17 pin)
Bit 5 reflects interrupt on GPIO_WKUP_2 (PSC3_9 pin)
Bit 6 reflects interrupt on GPIO_WKUP_1 (PSC2_4 pin)
Bit 7 reflects interrupt on GPIO_WKUP_0 (PSC1_4 pin)
