Microcontrollers Debugger Manual

Usage

NB [base]

Where base is the new number base (2, 8, 10 or 16).

Components

Debugger engine.

Table Example:

0x2F00, /* Hexadecimal Constant */

043, /* Octal Constant */

255 /* Decimal Constant */

In the same way, the Assembler notation for constant is also supported. That

means that independent of the current number base you can specify hexadecimal,

octal or binary constants using the Assembler prefixes shown in Table 34.7

Table Example:

$2F00, /* Hexadecimal Constant */

@43, /* Octal Constant */

%10011 /* Binary Constant */

When the default number base is 16, constants starting with a letter A, B, C, D, E

or F must be prefixed either by 0x or by $, as shown in Table 34.8

. Otherwise, the

command line interpreter cannot detect if you are specifying a number or a symbol.

Notation Meaning

0x---- Hexadecimal constant

0---- Octal constant

@---- Octal constant

%---- Binary constant
