The Integration Test ATB Control Register 0, ITATBCTR0, captures the values of the ATVALIDS, AFREADYS, and ATBYTESS inputs to the TPIU. To ensure the integration registers work correctly in a system, the value of ATBYTESS is only valid when ATVALIDS, bit 0, is HIGH. Figure 3.9 shows the bit assignments.
Table 3.9 shows the bit assignments.

| [9] | ATBYTES[1] | Read the value of ATBYTESS[1]. |
| [8] | ATBYTES[0] | Read the value of ATBYTESS[0]. |
| [7:2] | - | Reserved. RAZ on reads, SBZP on writes. |
| [1] | AFREADY | Read the value of AFREADYS. |
