Clarifications/Corrections to the Data
Sheet:
In the MCP2150 and MCP2155 device data sheets
(DS21655B and DS21690A), the following clarifications
and corrections should be noted:

DS80262A-page 2
An IrDA standard operating system (Symbian
OS™ for cell phones) has been encountered
that only sends out XID commands with a
Timeslot of 0. Since the MCP215X devices
respond to Timeslot 2, MCP215X devices are
not able to establish a link to an OS that is com-
pliant with the IrDA standard. The MCP2140 can
be used in these systems, since it responds to
the XIP command with Timeslot 0.
The MCP2150 emulates the state of all the non-
data circuits (CTS, RTS, DTR, DSR, CD and RI).
These signals on the MCP2150 are used to
interface with the embedded system’s host
controller. The values in the IrDA standard
packet response would not reflect the value on
the corresponding MCP2150 pin.
The MCP2155 emulates the state of the CTS, RTS
and DSR non-data circuits. These signals on the
MCP2155 are used to interface with the
embedded system’s host controller. The DTR, CD
and RI signal values are communicated to the IrDA
standard Primary device in an IrCOMM packet.
The MCP2155 will only send this information when
the state of one of these signals change. The
MCP2155 devices will ignore any request for the
status of the non-data circuits from the IrDA
standard Primary device.
