Conventions and Notations
The following sections explain the conventions used throughout this manual.
1.6.1 Pin Names
Pins are identified by their pin names or ball references. All active-low signals are identified by the suffix ‘#’ in their
names (e.g., SYSRESET#).
1.6.2 Pin Types
The pins are assigned different codes according to their operational characteristics. These codes are listed in
.
1.6.3 Numeric Representation
Hexadecimal numbers are appended with “h” whenever there is a risk of ambiguity. Other numbers are in decimal.
Pins of identical functions but different trailing digits (e.g., DFT_GPIO0, DFT_GPIO1, ...DFT_GPIO5) are referred to
collectively by specifying their digits in square brackets and with colons (i.e., “DFT_GPIO[5:0]”). 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.
