Conventions and Notations
1.9 Conventions and Notations
The following conventions are used throughout this manual.
1.9.1 Pin Names
Pins are identified by their pin names or ball references. Multiplexed pins assume alternate “functional names” when they
perform their alternate functions, and these “functional names” are given in
Chapter 3, “Pin Descriptions and Strap
Options.”
All active-low signals are identified by the suffix ‘#’ in their names (e.g., LDTSTOP#).
1.9.2 Pin Types
The pins are assigned different codes according to their operational characteristics. These codes are listed in Table 1-2 .
1.9.3 Numeric Representation
Hexadecimal numbers are appended with “h” (Intel assembly-style notation) whenever there is a risk of ambiguity. Other
numbers are in decimal.
Pins of identical functions but different trailing integers (e.g., “CPU_D0, CPU_D1,... CPU_D7”) are referred to
collectively by specifying their integers in square brackets and with colons (i.e., “CPU_D[7:0]”). A similar short-hand
notation is used to indicate bit occupation in a register. For example, NB_COMMAND[15:10] refers to the bit positions
10 through 15 of the NB_COMMAND register.
