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 = 004\h to 1FC\h.
Write only.
The Connection Memory enables the CPU to program which channel should be monitored. Up to 127 channels among 64k
can be programmed. To each channel one block size is associated.
Channel 1 corresponds to address = 004\h,
Channel 127 corresponds to address = 1FC\h.
This correspondence has to be kept in mind when CPU reads channel counter.(See later)
BIT

DESCRIPTION
