bit_word_offset = (byte_offset x 32) + (bit_number x 4)
bit_word_addr = bit_band_base + bit_word_offset
where:
Bit_word_offset is the position of the target bit in the bit-band memory region.
Bit_word_addr is the address of the word in the alias memory region that maps to the targeted bit.
Bit_band_base is the starting address of the alias region.
Byte_offset is the number of the byte in the bit-band region that contains the targeted bit.
Bit_number is the bit position, 0-7, of the targeted bit.
Figure 2.1 (p. 19) shows examples of bit-band mapping between the SRAM bit-band alias region
and the SRAM bit-band region:
The alias word at 0x23FFFFE0 maps to bit[0] of the bit-band byte at 0x200FFFFF: 0x23FFFFE0 =
0x22000000
+ (0xFFFFF*32) + (0*4).
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).

1MB SRAM bit -band region
2.2.5.1 Directly accessing an alias region
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.
