MEMORY LOACTIO HELP

[mikeb]

HELLLO BODGY THANKS MUCH FOR THE INFO YOU GAVE ME CONCERNING THE LCD AN FCC INSTRUCTION NOT USING THE HC11 THE ANSWERS YOU GAVE ME HELPED ME A LOT I WAS ABLE TO NARROW DOWN THE CAUSE OF WHY THE DISPLAY IS NOT RESPNDING TO THE MEMORY LOACTIONS, SO NOW I THINK MY QUESTION IS A BASCI ONE THAT PERTAINS TO NAY MICROCONTROLLER, THE QUESTION BEING ; THE TRAINER BAORD IM USING HAS A SOCKET FOR PUTTING IN AN EXTERNAL EPROM TO RUN YOUR CODE, BY DESIGN YOU ARE NOT ABLE TO ACCESS THE INTERNAL MEMORY ADDRESSES OF THE CONTROLLER, THEY ARE USED BY THE CODE TO SETUP CRITICAL ROUTINES FOR ILLEGAL OPCODE COP AND TIMER FAILURE. THE BOARD HAS USABLE MEMORY AT 2 DIFFERNT LOACATION THAT CAN BE ACCESSED BY THE EPROM THAT CONTAINS MY CODE, MY QUESTION IF YOU HAVE THE ANSWER IS ONE MEMORY LOACTION IS AT $0200 TO $0FFF AND $1040 TO $1FFF, IM WONDERING WHERE SHOULD I LOACTE THE STACK. AND IS IT DETERMINED BY WHAT LOCATION OF MEMORY I USED. <p>EXAMPLE: LDS #$0FFF THIS IS THE 1ST MEMORY LOCATION TOP OF RAM IF I USE $0200 TO $0FFF OR
LDS #$1FFF THIS IS THE 2ND MEMORY LOCATION TOP OF RAM ADDRESS $1040 TO $1FFF

I know nothing about the HC11. It would appear you have two banks of memory. As to stack location, put it in bank 0 if possible.
See if you have bank switching codes available.
