Description
Reserved. Returns 0 on read.
Power Mode 2. Controls clock behavior for the USB Core.
00: Disable clock gating. Clocks are always on.
01: Enable active hardware clock gating. Clock goes off whenever this module’s circuits
10: Reserved.
11: Reserved.
Description
System Error Enable. Write 1 to enable SYS_ERR_FLAG (bit 42) and to allow the
event to generate an ERR.
Parity Error In Enable. Write 1 to enable PARIN_ERR_FLAG (bit 41) and to allow the
event to generate an ERR.
Parity Error Out Enable. Write 1 to enable PAROUT_ERR_FLAG (bit 40) and to allow
the event to generate an ERR.
Timeout Error Enable. Write 1 to enable TIMEOUT_ERR_FLAG (bit 39) and to allow
the event to generate an ERR.
PCI Adapter Slave Interface Address Parity Error Enable. Write 1 to enable
PA_SVADRS_ERR_FLAG (bit 38) and to allow the event to generate an ERR.
PCI Adapter Target Abort Error Enable. Write 1 to enable PA_TABORT_ERR_FLAG
(bit 37) and to allow the event to generate an ERR.
PCI Adapter Master Abort Error Enable. Write 1 to enable
PA_MABORT_ERR_FLAG (bit 36) and to allow the event to generate an ERR.
Exception Bit Error Enable. Write 1 to enable EXCEP_ERR_FLAG (bit 35) and to
allow the event to generate an ERR.
Reserved. Writes don’t care. Reads return zero.
Unexpected Type Error Enable. Write 1 to enable UNEXP_TYPE_ERR_FLAG (bit
32) and to allow the event to generate an ERR.
