Is there a GPIO port that can be transparently transmitted between DS90UB947 and DS90UB948? For example, GPIO1 of 947 can be transparently transmitted to GPIO1 of 948 through FPDLINK, and there is such a corresponding GPIO between 947 and 948.

Hello Meng,
you can use any of GPIO0-3 for this purpose.
Hi Meng,
Please check the datasheets where you have the required information, and see the following register descriptions:
947 - Register 0x0F
948 - Register 0x1F
