undocumented CHIP_ID, MANUFACTURER_ID ??? for ICM20602

By adib1024 , 7 September 2018

Dear Invensense team,

looking at the datasheet for the ICM20602 there is only possibility for WHO_AM_I register identification.
DS-000176-ICM-20602-v1.0.pdf
And the first register starts with address 04h.

looking at the given ICM20602_eMD_nucleo_1.7 code, I see access to more identification possibilities not mentioned in datasheet.
"""
#define MPUREG_MANUFACTURER_ID 0x00
#define MPUREG_CHIP_ID 0x01
#define MPUREG_REVISION_ID 0x02
"""

Is there a datasheet that describes that values?
Is it save to access those registers?
Where is the most recent information?

Regards, Adib.
