1.4 STYLE AND SYMBOL CONVENTIONS
Throughout this document, certain style and font format conventions are used. Table 1-1
provides a description of the conventions used in this document.
Table 1-1: Document Conventions
Symbol or Term Description
set To force a bit/register to a value of logic ‘1’.
clear To force a bit/register to a value of logic ‘0’.
Reset 1. To force a register/bit to its default state.
2. A condition in which the device places itself after a device Reset
occurs. Some bits will be forced to ‘0’ (such as interrupt enable bits),
while others will be forced to ‘1’ (such as the I/O data direction bits).
0xnnnn Designates the number ‘nnnn’ in the hexadecimal number system. These
conventions are used in the code examples. For example, 0x013F or
0xA800.
: (colon) Used to specify a range or the concatenation of registers/bits/pins.
One example is ACCAU:ACCAH:ACCAL, which is the concatenation of
three registers to form the 40-bit Accumulator.
Concatenation order (left-right) usually specifies a positional relationship
(MSb to LSb, higher to lower).
< > Specifies bit locations in a particular register.
One example is SR<7:5> (or IPL<2:0>), which specifies the register and
associated bits or bit locations.
LSb, MSb Indicates the Least Significant or Most Significant bit in a field.
LSB, MSB Indicates the Least/Most Significant Byte in a field of bits.
lsw, msw Indicates the least/most significant word in a field of bits
Courier New
Font
Used for code examples, binary numbers and for Instruction mnemonics
in the text.
Times New
Roman Font, Italic
Used for equations and variables.
Times New
Roman Font,
Bold Italic
Used in explanatory text for items called out from a figure, equation, or
example.
Note: A Note presents information that we want to re-emphasize, either to help
you avoid a common pitfall, or make you aware of operating differences
between some device family members. A Note can be in a box, or when
used in a table or figure, it is located at the bottom of the table or figure.
