Getting invalid device id and package data values

I am getting invalid values for the device id and package data from the STM32WB55 on a P-NUCLEO-WB55 Nucleo board.

I am getting a value of 0x26 for the Device ID in the UID64 at 0x1FFF7584. And I am getting a value of 0x13 for the package type in the Package Data register at 0x1FFF7500.

According to the STM32WB55xx reference manual (RM0434), the device id is supposed to be 0x25. Also, the value of 0x13 does not correspond to any package type.

Which is the correct value? Is the error in the reference manual or on-chip?

That's interesting. The USB.dongle (with the QFN48). reports: 0x26 for the ID and 0x0A for the package.
