Numeric Values
Binary values are prefixed with 0b; for example, 0b00001000.
Hexadecimal values are expressed with UPPERCASE letters and prefixed with 0x; for
example, 0x0FBC.
All numeric values not specifically identified with the above prefixes as either binary or
hexadecimal are decimal values.
Registers and bit fields with 0b0 in all bits are referred to as ‘cleared’ or as 0. Registers and
bit fields with 0b1 values in all bits are referred to as ‘set’ or as the binary, hexadecimal, or
decimal value of the entire field or register.
Block Diagrams
The functional descriptions in this Guide include block diagrams with symbols representing
logical or mathematical operations or selections, usually the result of writing a value to a
register. Figure 1 shows one such multiplexer with three inputs and one output (the result).
Block diagrams can include symbols representing Registers and the bit fields within them.
Figure 2 shows that the BITFIELDNAME bit field in the REGISTERNAME register enables
or disables the signal named OUTPUT.
