CTIGATE, CTI Channel Gate Enable register
The CTIGATE characteristics are:
Determines whether events on channels propagate through the CTM to other ECT components, or from the CTM into the CTI.
CTIGATE is in the Debug power domain. RW fields in this register reset to architecturally UNKNOWN values. These apply only on an External debug reset. The register is not affected by a Warm reset and is not affected by a Cold reset.
CTIGATE is a 32-bit register.
The CTIGATE bit assignments are:
|GATE<x>, bit [x]|
GATE<x>, bit [x], for x = 0 to 31
Channel <x> gate enable.
Bits [31:N] are RAZ/WI. N is the number of ECT channels implemented as defined by the CTIDEVID.NUMCHAN field.
Possible values of this bit are:
Disable output and, if CTIDEVID.INOUT == 0b01, input channel <x> propagation.
Enable output and, if CTIDEVID.INOUT == 0b01, input channel <x> propagation.
If GATE[x] is set to 0, no new events will be propagated to the ECT, and if the ECT supports multicycle channel events any existing output channel events will be terminated.
On a External debug reset, this field resets to an architecturally UNKNOWN value.
Accessing the CTIGATE
CTIGATE can be accessed through the external debug interface:
This interface is accessible as follows:
- When SoftwareLockStatus() access to this register is RO.
- When !SoftwareLockStatus() access to this register is RW.
