Hello Arai,
Thank you for posting on Infineon Community.
Q) Please tell me the pin processing when the following pins are not used.
・ SAFE_PWR_EN (4 pin)
A) As this is a gate driver output, it is a programmable current sink.
It can be either pull-up or pull-down depending on the status of the Type-C negotiation.
・ GPIO_1 (8 pins)
A) If not enabled, as this is a standard GPIO, it will be high-Z analog.
Best regards,
Pablo
