13.8.51. Integration Instruction ATB In Register

The TRCITIATBINR characteristics are:

Purpose

Reads the state of the input pins shown in Table 13.54.

Usage constraints
  • Available when bit[0] of TRCITCTRL is set to 1.

  • The values of the register bits depend on the signals on the input pins when the register is read.

Configurations

Available in all configurations.

Attributes

See the register summaries in Table 13.3.

Figure 13.53 shows the TRCITIATBINR bit assignments.

Table 13.54 shows the TRCITIATBINR bit assignments.

Table 13.54. TRCITIATBINR bit assignments
BitsNameFunction
[31:2]-Reserved. Read undefined.
[1]AFVALIDMReturns the value of the AFVALIDMn input pin[a].
[0]ATREADYMReturns the value of the ATREADYMn input pin[a].

[a] When an input pin is LOW, the corresponding register bit is 0.

When an input pin is HIGH, the corresponding register bit is 1.

The TRCITIATBINR bit values always correspond to the physical state of the input pins.


The TRCITIATBINR can be accessed through the external debug interface, offset 0xEF4.
