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:
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=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=1 and WKUP-INT=0 only an interrupt on
channel INTD1 is generated.
If WUMx is reset, no wake-up events can be gen-
erated.
If WUMx is reset, no wake-up events can be gen-
erated.
