0x8FF

Start of ATmega328 hardware stack

0x900 - 0x1FFF

ceForth_328 dictionary

The parameter stack and return stack are allocated by the C compiler as parts of the FORTH Virtual Machine.

We do not have to worry about them in FORTH.

We are now starting compiling new commands into the target dictionary. First, the assembly command ORG in cefMETA328.f initializes the dictionary pointer, h, to memory location $920. The memory area below $900 is mapped to the RAM memory space. The memory area from $900 to $91F stores initial values of the boot up address and system variables In the cefMETA328.f file, the following lines of commands compiles the kernel of ceForth_328.
