Identifying a TI Chip

I am currently reverse engineering the Bosch Smart Home Controller II to get firmware details so projects like Zigbee2MQTT or Home Assistant ZHA can perform OTA Upgrades because Bosch won't release the update files.

I have probed many pins on the board, but I cant seem to find a JTAG, UART or something similar.

Since I cannot find anything about the TI chip that is used in the SHCII anywhere on the web, I thought I would ask here.

You may see the chip on the attached Picture, but here are the markings:

TI Logo SN15065260BZCZ 6CA6NXW GI 962B ZCZ

I already used the TI part lookup tool, but I didn't get any results there.
