Evaluation system. One of the range of platforms provided by Freescale for
evaluation and emulation of their devices.
High-density complementary metal oxide semiconductor. A semiconductor
technology chosen for its low power consumption and good noise immunity.
Input/output; used to describe a bidirectional pin or function.
(IC) This is a function provided by the timing system, whereby an external
event is ‘captured’ by storing the value of a counter at the instant the event
is detected.
This refers to an asynchronous external event and the handling of it by the
MCU. The external event is detected by the MCU and causes a
predetermined action to occur.
Interrupt request. The overline indicates that this is an active-low signal
format.
A kilo-byte (of memory); 1024 bytes.
Liquid crystal display.
Least significant byte.
Freescale’s family of 8-bit MCUs.
Microcontroller unit.
Interconnect bus. A single wire, medium speed serial communications
protocol.
Most significant byte.
Half a byte; four bits.
Non-return to zero.
The opcode is a byte which identifies the particular instruction and operating
mode to the CPU. See also: prebyte, operand.
The operand is a byte containing information the CPU needs to execute a
particular instruction. There may be from 0 to 3 operands associated with an
opcode. See also: opcode, prebyte.
(OC) This is a function provided by the timing system, whereby an external
event is generated when an internal counter value matches a predefined
value.
Plastic leaded chip carrier package.
Phase-locked loop circuit. This provides a method of frequency
multiplication, to enable the use of a low frequency crystal in a high
frequency circuit.
This byte is sometimes required to qualify an opcode, in order to fully specify
a particular instruction. See also: opcode, operand.
