CMT SW is based on HD943.  This product program has added internal data
functionality and ECI message interface.

External devices can be connected through serial cable (DLR–2) or IR.  The
protocols used are:

IrOBEX (ir–connectivity),

UltraIR (DCT3 connectivity),

IrDA (PC–connectivity)

 IrTranP (camera connectivity).

The PC connectivity uses a specific PCCOM protocol on top of the IrDA or seri-
al connection.

PDA and CMT processors interface through serial FBUS channel. On top of the
physical FBUS link two separate protocols are used. The Phonet protocol is
used to transport CMT related control information and data–frames. ”RBUS” is
used to transport ECI (External Control Interface) messages between PDA UI
and CMT.

CMT sw/hw interface is the same as hd940 is using.

PDA software is running on AMD Elan SC450 processor. Operating frequency
is 33MHz.
