Glossary

little endian: An addressing protocol in which bytes are numbered from right

to left within a word. More significant bytes in a word have higher-num-

bered addresses. Endian ordering is specific to hardware and is deter-

mined at reset. See also big endian.

µ-law companding: See compress and expand (compand).

maskable interrupt: A hardware interrupt that can be enabled or disabled

through software.

MCBSP: See multichannel buffered serial port; see also MCBSP module.

MCBSP module: MCBSP is an API module that contains a set of functions

for configuring the McBSP registers.

memory map: A graphical representation of a computer system’s memory,

showing the locations of program space, data space, reserved space,

and other memory-resident elements.

memory-mapped register: An on-chip register mapped to an address in

memory. Some memory-mapped registers are mapped to data memory,

and some are mapped to input/output memory.

most significant bit (MSB): The highest order bit in a word.

multichannel buffered serial port (McBSP): An on-chip full-duplex circuit

that provides direct serial communication through several channels to

external serial devices.

multiplexer: A device for selecting one of several available signals.

nonmaskable interrupt (NMI): An interrupt that can be neither masked nor

disabled.

object file: A file that has been assembled or linked and contains machine

language object code.

off chip: A state of being external to a device.

on chip: A state of being internal to a device.
