/**
 * There is a good chance the PY32F002A you got is a relabeled PY32F003X6
 * or PY32F030X6, this code will test the hidden resources of PY32F002A
 * 
 * 1. Fill flash to 32KB
 * 2. Fill RAM to 4KB
 * 3. Enable PLL to make system clock run at 48MHz
 * 
 * Notes:
 * 
 * 1. Before compiling, edit Makefile, change all options to PY32F030X6 
 *    instead of PY32F002A
 * 2. In case the code size exceed 32KB, edit dummy_data.h and dummy_data.c
 *    to shrink the array size.
