The TRCITIATBOUTR characteristics are:
- Purpose
Sets the state of the output pins shown in Table 13.55.
- Usage constraints
Available when bit[0] of TRCITCTRL is set to 1.
The value of the register sets the signals on the output pins when the register is written.
- Configurations
Available in all configurations.
- Attributes
See the register summaries in Table 13.3.
Figure 13.54 shows the TRCITIATBOUTR bit assignments.
Table 13.55 shows the TRCITIATBOUTR bit assignments.
| Bits | Name | Function |
|---|---|---|
| [31:10] | - | Reserved. Read undefined. |
| [9:8] | BYTES | Drives the ATBYTESMn[1:0] output pins[a]. |
| [7:2] | - | Reserved. Read undefined. |
| [1] | AFREADY | Drives the AFREADYMn output pin[a]. |
| [0] | ATVALID | Drives the ATVALIDMn output pin[a]. |
[a] 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 TRCITIATBOUTR bit values always correspond to the physical state of the output pins. | ||
The TRCITIATBOUTR can be accessed through the external debug
interface, offset 0xEFC.
