14.2.2 2K87M Mask Set Dual-Port RAM Memory Map
Figure 12 shows the MSC8103 2K87M mask set memory map of the dual-port RAM.
14.3 IMA Functionality
IMA functionality is similar to the updated functionality described in MPC8266AUMAD/D for updates to the
MPC826x product family. This document can be accessed from the Freescale website listed on the back page of
this document.
14.4 TSA Changes
The 2K87M mask set adds functionality required to support the new ATM transmission convergence (TC) layer
added to the communications processor module (CPM) in the time-slot assigner (TSA). This functionality can only
be configured and used by the fast communications controller 2 (FCC2) for ATM interfaces using the IMA
functionality.
