Triggered Transfer (TTF) support
Triggered Transfer (TTF) with TriCore and XC2000/XE166 microcontrollers uses a feature of these microcontrollers to reach a high polling performance and is only available with these microcontrollers. It allows the transfer of a value of a single memory location via the JTAG debug interface. The transfer is triggered by a debug event of the on-chip debug support (OCDS) unit. Using the UAD2, a sampling period in the range of 1 millisecond (1 ms) is assured for snapshots of the actual content of the instruction pointer in a selectable period during running target program. The recording is done while the target system is in running state.
UDE TTF Recorder of the Universal Debug Engine uses the Triggered Transfer Feature of Infineon microcontrollers.
