WRONGSIZE
A bus fault resulted from an 8-bit or 16-bit read or write of an APB peripheral register. This
fault can also result from an unaligned 32-bit access.
PROTECTED
A bus fault resulted from a user mode (unprivileged) write to a system APB or AHB peripheral
or protected RAM.
RESERVED
A bus fault resulted from a read or write to an address within an APB peripheral's 4-Kbyte
block range, but above the last physical register in that block. Can also result from a read or
write to an address above the top of RAM or flash.
MISSED
A bus fault occurred when a bit was already set in this register.
