CoreSight SoC Technical Reference Manual: 3.7.4. Integration Test ATB Control 2 Register

The ITATBCTR2 Register characteristics are:

Purpose

The Integration Test ATB Control 2 Register performs different functions depending on whether the access is a read or a write:

a write outputs data on atreadysn and afvalidsn, where the value of the ATB Funnel Control Register at 0x000 defines n.
a read returns the data from atreadym and afvalidm.

Usage constraints

There are no usage constraints.

Configurations

This register is available in all configurations.

Attributes

See the register summary in Table 3.35.

Bits Name Function

[31:2]

Reserved

Bits	Name	Function
[31:2]	Reserved	-
[1]	AFVALID	A read access returns the value of afvalidm. A write access outputs the data to afvalids`n`, where the value of the ATB Funnel Control Register at `0x000` defines n. The possible values are: 0 Pin is at logic 0. 1 Pin is at logic 1.
[0]	ATREADY	A read access returns the value of atreadym. A write access outputs the data to atreadys`n`, where the value of the ATB Funnel Control Register at `0x000` defines n. The possible values are: 0 Pin is at logic 0. 1 Pin is at logic 1.
