+These mutually-exclusive flags configure the initial direction of the
pins. PORTMUX_DIR_OUTPUT means that the pins are driven by the CPU,
while PORTMUX_DIR_INPUT means that the pins are tristated by the CPU.
These flags are ignored by portmux_select_peripheral().

+These mutually-exclusive flags determine the drive strength of the
pins. PORTMUX_DRIVE_MIN will give low power-consumption, but may cause
corruption of high-speed signals. PORTMUX_DRIVE_MAX will give high
power-consumption, but may be necessary on pins toggling at very high
