3313D–USB–04/06
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
Register allows the microcontroller to control when it wants visibility to an interrupt. 1 = Enable
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
