SPAN
Span Increment Register
This is a signed number in range [-128,127] for use in spanned address mode. If
destination or source addressing mode is set as spanned, then this number is added
to the address register each transfer. The size of the transfer is determined by the
APB_TW setting. Note that span increment must be a multiple of the transfer width
otherwise a memory addressing HardFault will occur. Also SPAN may be a negative
number.
