KWIE – Key Wake-up Enable
Key Wake-up Interrupt (KWI) Enable bit enables Key Wake-up Interrupt when
KWIF is set. This bit is cleared on reset.
0 =
KWI is disabled
1 =
KWI is enabled
IRQ1S – IRQ1 Select Edge Sensitive Only
0 =
IRQ1 is congured for low LEVEL and negative edge sensitive
1 =
IRQ1 is congured to respond only to negative EDGEs
IRQ2S – IRQ2 Select Edge Sensitive Only
0 =
IRQ2 is congured for low LEVEL and negative edge sensitive
1 =
IRQ2 is congured to respond only to negative EDGEs
4.4.8 Interrupt Status Register (INTSR)
IRQ1F – IRQ1 Interrupt Flag
When IRQ1S = 0, the falling edge or low level at IRQ1 pin sets IRQ1F. When
IRQ1S = 1, only the falling edge at pin sets IRQ1F bit. If IRQ1E bit and this bit
are set, an interrupt is generated. This bit is read only bit and cleared by writing
a 1 to the RIRQ1 bit. Reset clears this bit.
IRQ2F – IRQ2 Interrupt Flag
When IRQ2S = 0, the falling edge or low level at IRQ2 pin sets IRQ2F. When
IRQ2S = 1, only the falling edge at pin sets IRQ2F bit. If IRQ2E bit and this bit
are set, an interrupt is generated. This bit is read only bit and cleared by writing
a 1 to the RIRQ2 bit. Reset clears this bit.
KWIF – Key Wake-up Interrupt Flag
When KWIE
x bit in the KWIEN register is set, the falling edge at KWIx pin sets
KWIF bit. If KWIE bit and this bit are set, an interrupt is generated. This bit is a
read only bit and clearing KWIF is accomplished by writing a 1 to the RKWIF
bit. Reset clears this bit.
RIRQ1 – Reset IRQ1 Flag
The RIRQ1 bit is a write only bit and always read as 0. Writing a 1 to this bit
clears the IRQ1F bit and writing 0 to this bit has no effect.
