IrDA DATA PROTOCOLS
SUPPORTED BY MCP2140
The MCP2140 supports these required IrDA standard
protocols:
Physical Signaling Layer (PHY)
Link Access Protocol (IrLAP)
Link Management Protocol/Information Access
Service (IrLMP/IAS)
The MCP2140 also supports some of the optional pro-
tocols for IrDA standard data. The optional protocols
implemented by the MCP2140 are:
Tiny TP
IrCOMM
Figure 2-7
shows the IrDA data protocol stack and
those components implemented by the MCP2140.

IRCOMM
IrCOMM provides the method to support serial and par-
allel port emulation. This is useful for legacy COM
applications, such as printers and modem devices.
The IrCOMM standard is a syntax that allows the Pri-
mary device to consider the Secondary device a serial
device. IrCOMM allows for emulation of serial or paral-
lel (printer) connections of various capabilities. The
MCP2140 supports the 9-wire “cooked” service class of
IrCOMM. Other service classes supported by IrCOMM
are shown in
Figure 2-8
.
The IrDA protocol for printer support is not included in
the IrCOMM 9-wire “cooked” service class.
