WAKE-UP / INTERRUPT LINES MANAGEMENT UNIT (Cont’d)
WAKE-UP MASK REGISTER HIGH (WUMRH)
R250 - Read/Write
Register Page: 57
Reset Value: 0000 0000 (00h)
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
– If ID1S=1 and WKUP-INT=0 only an interrupt on
If WUMx is reset, no wake-up events can be gen-
erated.
