CTIGATE, CTI Channel Gate Enable register

The CTIGATE characteristics are:

Purpose

Determines whether events on channels propagate through the CTM to other ECT components, or from the CTM into the CTI.

Configuration

CTIGATE is in the Debug power domain.

Attributes

CTIGATE is a 32-bit register.

Field descriptions

The CTIGATE bit assignments are:

GATE<x>, bit [x], for x = 31 to 0

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.

GATE<x>Meaning
0b0

Disable output and, if CTIDEVID.INOUT == 0b01, input channel <x> propagation.

0b1

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 an External debug reset, this field resets to an architecturally UNKNOWN value.

Accessing the CTIGATE

CTIGATE can be accessed through the external debug interface:
