3302E–USB–7/04
Suspend/Resume Interrupt Enable Register – SPRSIE
Bit 7..4 – Res: Reserved Bits
These bits are reserved and are always read as zeros.
Bit 3 – BUS INT EN: USB Reset Interrupt Enable
When the BUS INT EN bit is set, the USB and microcontroller resets are separated. A USB
bus reset will reset the USB hardware only and not the microcontroller. However, an interrupt
to the microcontroller 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.
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..4 – Res: Reserved Bits
These bits are reserved and are always read as zeros.
Bit 3 – BUS INT MSK: USB Reset Interrupt Mask
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
