Terminology Usage
Attention! The term
Use of reserved areas can cause compatibility problems, loss of data, or permanent damage to the hardware. When the contents of a register are changed, the state of the reserved bits must be preserved. When possible, read the register first and change only the bits that must be changed.
In this manual, some signals are represented in a small, all-capital-letter format (-ACK). A minus sign in front of the signal indicates that the signal is active low. No sign in front of the signal indicates that the signal is active high.
The use of the term “M” and “G“ are used, they typically indicate powers of 2, not powers of 10. For example, 1 KB equals 1024 bytes (210), 1 MB equals 1 048576 bytes (220), and 1 GB equals 1073741824 bytes (230).
When expressing storage capacity, MB equals 1000 KB (1024000). The value is determined by counting the number of sectors and assuming that every two sectors equals 1 KB.
Note: Depending on the operating system and other system requirements, the storage capacity available
to the user might vary.
