The USBSysErrIntSt is a read only register.Table 222: USB System Error Interrupt Status register (USBSysErrIntSt - address0xE009 00B8) bit descriptionBit Symbol Value Description Resetvalue31:0 EPxx Endpoint xx (0 ≤ xx ≤ 31) System Error Interrupt request. 00 There is no System Error Interrupt request for endpoint xx.1 There is a System Error Interrupt request for endpoint xx.14.8.27 USB System Error Interrupt Clear register (USBSysErrIntClr -0xE009 00BC)Writing 1 into the register will clear the corresponding interrupt from the System ErrorInterrupt Status register. Writing 0 will not have any effect. The USBSysErrIntClr is a writeonly register.Table 223: USB System Error Interrupt Clear register (USBSysErrIntClr - address0xE009 00BC) bit descriptionBit Symbol Value Description Resetvalue31:0 EPxx Clear endpoint xx (0 ≤ xx ≤ 31) System Error Interrupt request. 00 Ne effect.1 Clear the EPxx System Error Interrupt request in theUSBSysErrIntSt register.14.8.28 USB System Error Interrupt Set register (USBSysErrIntSet -0xE009 00C0)Writing 1 into the register will set the corresponding interrupt from the System ErrorInterrupt Status register.
