Performance Monitor Register

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 = 000\h to 07C\h.
Write only.
The Connection Memory enables the CPU to program which connection should be monitored. Up to 32 connections can be
programmed. To each connection one block size is associated.
Connection 0 corresponds to address = 000\h,
Connection 31 corresponds to address = 07C\h.
This correspondence has to be kept in mind when CPU reads Connection counter.(See later)
BIT

DESCRIPTION
Any PM_Connection number can be written from 1 to 127.
PM_Connection 00\h is not an active connection.

Block size associated to the channel programmed :
00 : 128 cells
01 : 256 cells
10 : 512 cells
11 : 1024 cells
