ID, [6:0]

Drives the ATIDMn[6:0] output pins.

When a bit is set to 0, the corresponding output pin is LOW.

When a bit is set to 1, the corresponding output pin is HIGH.

The TRCITATBIDR bit values correspond to the physical state of the output pins.

Bit fields and details not provided in this description are architecturally defined. See the Arm® Architecture Reference Manual Armv8, for Armv8-A architecture profile.

The TRCITATBIDR can be accessed through the external debug interface, offset 0xEE4.
