AT43USB320A
1443E–USB–4/04
Suspend/Resume Interrupt Enable Register – SPRSIE
Bit 7..3 – 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 (SE0 for longer than 3 ms) will reset the USB hardware only and not the microcon-
troller. 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.
