APPENDIX D
MC68MH360 PRODUCT BRIEF
The MC68MH360 is a derivative of the MC68360 QUICC.
QUICC32.
The QUICC32 has some modifications in the Communication Processor Module (CPM)
hardware and a larger internal dual port RAM. These hardware changes in combination with
a new ROM based microcode, called QMC (QUICC Multichannel Controller), emulates up
to 32 HDLC channels within one SCC. The MH360 is ideal in primary rate ISDN applications
and interfaces directly to a E1/T1 line and is capable of terminating all time slots using HDLC
or transparent mode of operation. One of the time slot assigners (SI) is dedicated to the use
of the QMC. The SI transfers the whole frame or selected time slots to one SCC. All other
features remain unchanged and the QUICC32 is pin compatible with the other family mem-
bers.
A QUICC32 in non-QMC mode has exactly the same functionality as a standard MC68360
with the exception that the Centronics and BISYNC protocols have been removed on the
QUICC32 to create ROM space for the QMC protocol.
