Data Format
To understand the format of the data within the block data, there are four
important things to keep in mind.
•Data is sent to the controller in binary form.
•Each byte, as described in this chapter, contains 8 bits.
•The first bit of each byte is the MSB (most significant bit).
•Byte descriptions are printed in binary, decimal, or ASCII depending on
how the data is described.
For example, the first ten bytes that describe the section name contain a
total of 80 bits as follows:
Binary 0100 0100 0100 0001 0101 0100 0100 0001 0010 0000 ... 0010 0000
Decimal 68 65 84 65 32 32 32 32 32 32
ASCII DATA space spac e space space spac e space
Byte 1 Byte 10
MSB LSB
