Additional memory

George Mylonas

Hi there

I've added some extra 64Kb of RAM on my KC167CR development board. This memory sould be \CS2 selectable at a starting address of 0x50000.

I got problems in selecting that RAM chip. The \CS2 is not going low is it should.

In C166 the memory settings are:

RAM1 (0x0000 to 0x10000) and
RAM2 (0x50000 to 0x60000)

In the monitor CONFIG.INC file the settings are:
%DEFINE (ADDRESS1) (0000H); Set CS1# Start Address 
%DEFINE (RANGE1)  (64K)       
.
.
%DEFINE (ADDRESS2) (50000H); Set CS2# Start Address
%DEFINE (RANGE2)   (64K)

But I cannot select the memory with \CS2.

Any ideas?
Thanks
George
