I am using the CCG3PA (CYPD3175) in a power adapter like design and I'd like to use one of the SWD pins as a GPIO. In particular, I'd like to use it to control a termination resistor to enable the Apple 2.4A charging mode (DP_APPLE_SRC_TERM_A).
I have found the setting for the Debug Select in PSoC Creator (as shown in the attached screenshot), but I cannot find any mention of this in the CCG3PA documentation. The note says to reference the Technical Reference Manual (TRM) but I cannot find a TRM for the CCG3PA.
My concern is that I won't be able to program the CCG3PA via SWD if I have other circuitry connected to those signals and I see no guidance in the documentation on how to handle this.
Typically, we do not recommend re-use SWD pins for other usage. But there are always short of pin on the application design, so that this IO could use as general GPIO. You could use it for external pull-up resistor of supporting Apple charging and BC1.2 serials.
