DigitalKey Standard (CCC/ICCE/ICCOA)

[Hyunjin1]

According to the URL below, it is mentioned that DigitalKey of NXP supports CCC, ICCOA, and ICCE standards.

I have some questions regarding this:

1. If a phone supports two standards (CCC and ICCE) and the car only supports the CCC standard, how do the each devices match on which standard to use? When the car sends a Select Request to the phone, does the phone recognize CCC standard by checking something like the DigitalKey AID?

2. Is it impossible to use a phone that only supports ICCE with a car that only supports CCC? or If I install a separate CCC-supporting app on the phone, can I use it with the CCC car?

CCC is global standard while ICCE is local standard and it may not compatible with each other
