# eligible. (1CH / 1CH_CMP are excluded; all others are fine.)

# --- Safety ---
# WARNING: this allows reusing SWD debug pins, which is dangerous!
# This HAL has no power-on delay, so reconfiguring SWD pins immediately on
# startup can permanently lock you out of reprogramming ("brick") the chip.
# The risk is critical on MCUs without a BOOT button and bootloader
# (e.g. PY32F002B, PY32L020, PY32C64x — on PA2 and PB6).
# Enable only if you understand the risk and have a recovery plan.
