Document Conventions
To force a bit/register to a value of logic ‘1’.
To force a bit/register to a value of logic ‘0’.
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).
Designates the number ‘nn’ in the hexadecimal number system. These
conventions are used in the code examples.
convention is used in the text and in figures and tables.
Read - Modify - Write. This is when a register or port is read, then the
value is modified, and that value is then written back to the register or
port. This action can occur from a single instruction (such as bit set file,
BSF) or a sequence of instructions.
Used to specify a range, or the concatenation of registers / bits / pins.
An example is TMR1H:TMR1L is the concatenation of two 8-bit registers
to form a 16-bit timer value, while SSPM3:SSPM0 are 4-bits used to
specify the mode of the SSP module. Concatenation order (left-right)
usually specifies a positional relationship (MSb to LSb, higher to lower).
Specifies bit(s) locations in a particular register.
An example is SSPCON<SSPM3:SSPM0> (or SSPCON<3:0>) specifies
the register and associated bits or bit positions.
Used for code examples, binary numbers, and for Instruction Mnemonics
in the text.
Used for equations and variables.
Used in explanatory text for items called out from a graphic/equa-
tion/example.
Notes present information that we wish to reemphasize, either to help
you avoid a common pitfall, or make you aware of operating differences
between some device family members. A Note is always in a shaded box
(as below), unless used in a table, where it is at the bottom of the table
(as in this table).
A caution statement describes a situation that could potentially damage
software or equipment.
A warning statement describes a situation that could potentially cause
personnel harm.
Designates the number ‘bbbbbbbb’ in the binary number system. This
