Bit field descriptions

The TRCITIATBOUTR is a 32-bit register.

Figure D8-43 TRCITIATBOUTR bit assignments


For all non-reserved bits:

  • 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.
[31:10]
Reserved. Read undefined.
BYTES, [9:8]
Drives the ATBYTESMn[1:0] output pins.
[7:2]
Reserved. Read undefined.
AFREADY, [1]
Drives the AFREADYMn output pin.
ATVALID, [0]
Drives the ATVALIDMn output pin.

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 TRCITIATBOUTR can be accessed through the external debug interface, offset 0xEFC.
