Terminology usage
Attention: The term
reserved
describes certain signals, bits, and registers that should not be changed.
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
hex
indicates a hexadecimal number.
