CAUTION
Serial interface test mode must be entered only when trace is not enabled and
the SDTI FIFO is empty. Switching to serial interface test mode while trace is
active leads to unpredictable results.
27.3.5.3 CoreSight Integration Mode Setup
To enable the serial CoreSight integration mode, perform the following steps:
1. If setup is performed through application software, enable write access to the SDTI by writing unlock
key to the lock access register ( LOCK_ACCESS_REG )
2. Switch to integration mode by setting the INT_MODE_CTRL_REG [0] ITM bit to 1.
3. The SDTI remains in Integration mode until INT_MODE_CTRL_REG [0] ITM is cleared to 0.
CAUTION
Integration mode must be entered only when trace is not enabled and the SDTI
FIFO is empty. Switching to integration mode while trace is active leads to
unpredictable results.
