Writing to a word in the alias region updates a single bit in the bit-band region.
Bit[0] of the value written to a word in the alias region determines the value written to the
targeted bit in the bit-band region. Writing a value with bit[0] set to 1 writes a 1 to the
bit-band bit, and writing a value with bit[0] set to 0 writes a 0 to the bit-band bit.
Bits[31:1] of the alias word have no effect on the bit-band bit. Writing 0x01 has the same
effect as writing 0xFF. Writing 0x00 has the same effect as writing 0x0E.

The alias word at 0x23FFFFFC maps to bit[7] of the bit-band byte at 0x200FFFFF:
0x23FFFFFC = 0x22000000 + (0xFFFFF*32) + (7*4).
The alias word at 0x22000000 maps to bit[0] of the bit-band byte at 0x20000000:
0x22000000 = 0x22000000 + (0*32) + (0 *4).
The alias word at 0x2200001C maps to bit[7] of the bit-band byte at 0x20000000:
0x2200001C = 0x22000000+ (0*32) + (7*4).
0x00000000 indicates that the targeted bit in the bit-band region is set to zero
0x00000001 indicates that the targeted bit in the bit-band region is set to 1
