Field Name | Bits | Type | Reset Value | Description |
EXLEVEL_NS | 23:20 | rwNormal read/write | 0x0 | In Non-secure state, each bit controls whether instruction tracing is enabled for the corresponding exception level:The exception levels are:Bit[20]Exception level 0.Bit[21]Exception level 1.Bit[22]Exception level 2.Bit[23]RAZ/WI. EXLEVEL_NS[3] is never implemented.The content of the field is IMPLEMENTATION DEFINED and is set by the value of IDR3.EXLEVEL_NS. If instruction tracing is not implemented for a given exception level, the corresponding bit in this field is not implemented. Unimplemented bits are RAZ/WI. |
EXLEVEL_S | 19:16 | rwNormal read/write | 0x0 | In Secure state, each bit controls whether instruction tracing is enabled for the corresponding exception level:The exception levels are:Bit[16]Exception level 0.Bit[17]Exception level 1.Bit[18]RAZ/WI. EXLEVEL_S[2] is never implemented.Bit[19]Exception level 3.The content of the field is IMPLEMENTATION DEFINED and is set by the value of IDR3.EXLEVEL_S. If instruction tracing is not implemented for a given exception level, the corresponding bit in this field is not implemented. Unimplemented bits are RAZ/WI. |
TRCERR | 11 | rwNormal read/write | 0 | Controls whether a trace unit must trace a system error exception |
TRCRESET | 10 | rwNormal read/write | 0 | Controls whether a trace unit must trace a Reset exception |
SSSTATUS | 9 | rwNormal read/write | 0x0 | Indicates the status of the start-stop logic |
TYPE | 7 | rwNormal read/write | 0x0 | Selects the rsource type for the viewinst event: 0-single selected resource, 1-Boolean combined resource pair |
SEL | 3:0 | rwNormal read/write | 0x0 | When TYPE is 0, selects a singal selected resource from 0-15 defined by bits[3:0]; when TYPE is 1, selects a Boolean combined resource pair from 0-7 define by bits[2:0]. |
