I'm making my own mini-board and I was wondering what would be the minimum number of pins that have to be interfaced with in order to always be able to program the chip, no matter the current state of the chip. This assumes that the chip is connected to a crystal and power is supplied.

I sometimes power a board via USB, and its onboard 3.3V reg, and then only connect the STLink via SDIO SCLK and Gnd.
