The first column shows the available memory in bytes.
The columns that follow show the various available access options (bit, byte, word, and
double word).
The first 64 bytes can be accessed with all four access options.
Within this context, M41 is the least significant bit of byte 4, the least significant bit of
MB5, the least significant bit of MW3, and the least significant bit of MD2.
Bit access ends at MB 64. After that point, access is only possible with bytes, words,
and double words.
Byte access ends at MB 512. After that point, access is only possible with words and
double words.
