Peripheral Width. For external DMA transfers, these bits
are used to program the DMA to request byte/half-
word/word wide AHB transfers, depending on the width of
the external device. These bits are not used for software
triggered M2M transfers.
00 - Byte (8 bits)
01 - Half-word (16 bits)
10 - Word (32 bits)
11 - Not used
For word accesses the lower 2 bits of the
source/destination address are ignored.
For half-word accesses the lower bit of the
source/destination address is ignored.
