11.3.7. Integration FIFO 1 Data

The Integration FIFO 1 Data characteristics are:

Purpose

Trace data integration testing.

Usage constraints

You must set bit [1] of TPIU_ITCTRL to use this register. See Integration Mode Control, TPIU_ITCTRL.

Configurations

This register is available in all processor configurations.

Attributes

BitsNameFunction
[31:30]-Reserved
[29]FIFO 1 ATVALID inputReturns the value of the FIFO 1 ATVALID2 signal.
[28:27]FIFO 1 byte countNumber of bytes of FIFO 1 trace data since last read of Integration ITM Data Register.
[26]FIFO 0 ATVALID inputReturns the value of the FIFO 0 ATVALID1 signal.
[25:24]FIFO 0 byte countNumber of bytes of FIFO 0 trace data since last read of Integration ETM Data Register.
[23:16]FIFO 1 data 2These fields contain ITM trace data if an ETM is present. The TPIU discards this data when the register is read.
[15:8]FIFO 1 data 1
[7:0]FIFO 1 data 0
