CTIINTACK, CTI Output Trigger Acknowledge register
The CTIINTACK characteristics are:
Can be used to deactivate the output triggers.
CTIINTACK is in the Debug power domain.
CTIINTACK is a 32-bit register.
The CTIINTACK bit assignments are:
|ACK<n>, bit [n]|
ACK<n>, bit [n], for n = 0 to 31
Acknowledge for output trigger <n>.
Bits [31:N] are RAZ/WI. N is the number of CTI triggers implemented as defined by the CTIDEVID.NUMTRIG field.
If any of the following is true, writes to ACK<n> are ignored:
- n >= CTIDEVID.NUMTRIG, the number of implemented triggers.
- Output trigger n is not active.
- The channel mapping function output, as controlled by CTIOUTEN<n>, is still active.
Otherwise, if any of the following are true, it is IMPLEMENTATION DEFINED whether writes to ACK<n> are ignored:
- Output trigger n is not implemented.
- Output trigger n is not connected.
- Output trigger n is self-acknowledging and does not require software acknowledge.
Otherwise, the behavior on writes to ACK<n> is as follows:
Deactivate the trigger.
Accessing the CTIINTACK
A debugger must read CTITRIGOUTSTATUS to confirm that the output trigger has been acknowledged before generating any event that must be ordered after the write to CTIINTACK, such as a write to CTIAPPPULSE to activate another trigger.
CTIINTACK can be accessed through the external debug interface:
This interface is accessible as follows:
- When SoftwareLockStatus() access to this register is WI.
- When !SoftwareLockStatus() access to this register is WO.
