Suspend/Resume Interrupt Enable Register – SPRSIE

• · Bit 7 – INTD EN: External Interrupt D Enable

Setting the INTD EN bit will initiate an interrupt whenever the INTD bit of SPRSR is set.

• · Bit 6 – INTC EN: External Interrupt C Enable

Setting the INTC EN bit will initiate an interrupt whenever the INTC bit of SPRSR is set.

• · Bit 5 – INTB EN: External Interrupt B Enable

Setting the INTD EN bit will initiate an interrupt whenever the INTB bit of SPRSR is set.

• · Bit 4 – INTA EN: External Interrupt A Enable

Setting the INTD EN bit will initiate an interrupt whenever the INTA bit of SPRSR is set.

• · Bit 3 – BUS INT EN: USB Reset Interrupt Enable

When the BUS INT EN bit is set, the USB and µC resets are separated. A USB bus reset (SE0

for longer than 3 ms) will reset the USB hardware only and not the µC. However, an interrupt to

the µC will be generated and bit 3 of SPRSR is set.

• · Bit 2 – FRWUP IE: Function Remote Wakeup Interrupt Enable

Setting the FRWUP IE bit will initiate an interrupt whenever the FRWUP bit of SPRSR is set.

• · Bit 1 – RSM IE: Resume Interrupt Enable

Setting the RSM IE bit will initiate an interrupt whenever the RSM bit of SPRSR is set.

• · Bit 0 – GLB SUSP IE: Global Suspend Interrupt Enable

Setting the GLB SUSP IE bit will initiate an interrupt whenever the GLB SUSP bit of SPRSR is

set.
