Bit 7:0 = WUM[15:8]: Wake-Up Mask bits.

If WUMx is set, an interrupt on channel INTD1

and/or a wake-up event (depending on ID1S and

WKUP-INT bits) are generated if the correspond-

ing WUPx pending bit is set. More precisely, if

WUMx=1 and WUPx=1 then:

– If ID1S=1 and WKUP-INT=1 then an interrupt on

channel INTD1 and a wake-up event are gener-

ated.

– If ID1S=1 and WKUP-INT=0 only an interrupt on

channel INTD1 is generated.

– If ID1S=0 and WKUP-INT=1 only a wake-up

event is generated.

– If ID1S=0 and WKUP-INT=0 neither interrupts

on channel INTD1 nor wake-up events are gen-

erated. Interrupt requests on channel INTD1 may

be generated only from external interrupt source

INT7.

If WUMx is reset, no wake-up events can be gen-

erated. Interrupt requests on channel INTD1 may

be generated only from external interrupt source

INT7 (resetting ID1S bit to 0).

Bit 7:0 = WUM[7:0]: Wake-Up Mask bits.

If WUMx is set, an interrupt on channel INTD1

and/or a wake-up event (depending on ID1S and

WKUP-INT bits) are generated if the correspond-

ing WUPx pending bit is set. More precisely, if

WUMx=1 and WUPx=1 then:

– If ID1S=1 and WKUP-INT=1 then an interrupt on

channel INTD1 and a wake-up event are gener-

ated.

– If ID1S=1 and WKUP-INT=0 only an interrupt on

channel INTD1 is generated.

– If ID1S=0 and WKUP-INT=1 only a wake-up

event is generated.

– If ID1S=0 and WKUP-INT=0 neither interrupts

on channel INTD1 nor wake-up events are gen-

erated. Interrupt requests on channel INTD1 may

be generated only from external interrupt source

INT7.

If WUMx is reset, no wake-up events can be gen-

erated. Interrupt requests on channel INTD1 may

be generated only from external interrupt source

INT7 (resetting ID1S bit to 0).
