How to activate ETM on M48x ?

Dear staffs,

Finally, I could obtain a Nuvoton's new great MCU chip M48x and its evaluation boards.
One of the most exciting new features is ETM, which had not been found on the other Nuvoton's Cortex-M MCUs.
To evaluate this feature very quickly, I got NuMaker-ETM-M487, on which ETM-connector is already mounted on the board.

Anyway, how can I activate and utilize it with may Keil MDK ARM + UlinkPro(ICE with ETM feature) ?

I've been searching for technical information about that thru NuMaker-ETM-M487 User manual(Rev.1.00) and Technical Reference Manual for M480 serise (Rev.1.01). But, no helpful information....

Even in Technical Reference manual, the only thing I could find was corresponding block called "ETMC" is placed near "SWDC".
Another interresting feature (just by name, now) is that DMA can be triggered by "ETMC_RX" as #65th request source.

Does anyone have helpful information about those?

To enable the ETM trace function, you need to add some code to switch the pin's multi-function to ETM trace pin at the initial state:
/* Setup ETM Pin Usage
- PE.8: DAT3
- PE.9: DAT2
- PE.10: DAT1
- PE.11: DAT0
- PE.12: CLK */
