Suspend/Resume Interrupt Enable Register – SPRSIE

• Bit 7..3 – Res: Reserved Bits

These bits are reserved and are always read as zeros.

• 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.

Suspend/Resume Interrupt Mask Register – SPRSMSK

The bits of the Suspend/Resume Mask Register are used to make an interrupt caused by an

event in the Suspend/Resume Register visible to the microcontroller. The Suspend/Resume

Interrupt Enable Register bits enable the interrupt while the Suspend/Resume Interrupt Mask

Mask, 0 = Disable Mask.

• Bit 7..3 – Res: Reserved Bits

These bits are reserved and are always read as zeros.

• Bit 2 – FRWUP MSK: Function Remote Wakeup Interrupt Mask

• Bit 1 – RSM MSK: Resume Interrupt Mask

• Bit 0 – GLB SUSP MSK: Global Suspend Interrupt Enable
