Register Address Map
The state of the CSN, RWN, and ADDRESS(10:0) signals determines which internal register the microprocessor addresses.
All registers access are modulo 32-bits address, i.e. address bit 0 and bit 1 are not used in decoding logic.

Connection memory
Address = 004\h to 1FC\h.
Write only.
The Connection Memory enables the CPU to program which connection should be monitored. Up to 127 connections can be
programmed. To each connection one block size is associated.
Connection 1 corresponds to address = 004\h,
Connection 127 corresponds to address = 1FC\h.
This correspondence has to be kept in mind when CPU reads connection counter.(See later)
BIT
0
DESCRIPTION
1 : Connection active.
0 : Connection inactive.
Block size associated to the Connection programmed :
00 : 128 cells
01 : 256 cells
10 : 512 cells
11 : 1024 cells
Not used.
