Definition of Terms
The
following
terms
are
used
throughout
this
document:
I/O Expander - refers to the integrated circuit (IC)
device being described (MCP2502X/5X).
Input Message - term given to messages that are
received by the MCP2502X/5X and cause the internal
registers to be modified. Once the register modification
has been performed, the MCP2502X/5X transmits a
Command Acknowledge message to indicate that the
command was received and processed.
Command Acknowledge Message - term given to the
message that is automatically transmitted by the
MCP2502X/5X after receiving and processing an input
message.
Information Request Message - term given to
Remote Request messages that are received by the
MCP2502X/5X that subsequently generate an output
message (data frame) in response.
Output Message - term given to the message that the
MCP2502X/5X sends in response to an Information
Request message.
On Bus Message - term given to the message that the
MCP2502X/5X transmits after completing the power-on/
self-configuration
sequence
at
timed
intervals,
if
enabled.
Self-Configuration - term used to describe the
process of transferring the contents of the EPROM
memory array to the SRAM memory array.
On Bus - term used to describe the condition when the
MCP2502X/5X
is
fully-configured
and
ready
to
transmit, or receive, on the bus. This is the only state in
which the MCP2502X/5X can transmit on the bus.
Edge Detection - refers to the MCP2502X/5X’s ability
to automatically transmit a message based upon the
occurance of a predefined edge on any digital input.
Threshold Detection - refers to the MCP2502X/5X’s
ability to automatically transmit a message when a
predefined analog threshold is reached.
