EN
Description:
Enable.
When this bit is set to one, the IPBus monitor is armed. Each time the trigger condition
specified by the TC field and the IPBus Monitor Trigger Select (IPBMTS) register are satisfied
the Trigger Count (TCOUNT) field is decremented. When the TCOUNT field reaches zero, the
enable bit is set to zero (cleared) and a final trigger event occurs.
Note
: When this bit is set, the IPBus records transactions until a final trigger event occurs or until
this bit is cleared by software.

RC
Description:
Recording Completed.
When the IPBus monitor completes storing transaction records in on-
chip memory (i.e., the space allocated by the FTRL field is exhausted) this bit is set.
Initial Value:
0x0
Read Value:

Write Effect:
Sticky bit (a sticky bit is set by the hardware and can only be cleared by the CPU)
RA
Description:
Rearm.
When this bit is set to one, the IPBus monitor is automatically rearmed (i.e., the enable
bit is set) after a final trigger event occurs. When the IPBus monitor is rearmed, the value in the
RTCOUNT field is loaded into the TCOUNT field.
Initial Value:
0x0

Write Effect:
Sticky bit (a sticky bit is set by the hardware and can only be cleared by the CPU)
TC
Description:
Trigger Condition.
When this bit is set to one, the IPBus monitor triggers when all of the
selected trigger conditions selected in the IPBMTS register are satisfied (i.e., AND of all enabled
trigger conditions). When this bit is cleared, the IPBus monitor triggers when any of the selected
trigger conditions are satisfied (i.e., OR of all enabled trigger conditions).
