Register and memory map
As shown in
registers.
The available memory locations consist of 128 bytes of register locations, up to 1024 bytes
of RAM and up to 32 Kbytes of user program memory. The RAM space includes up to 256
bytes for the stack from 0100h to 01FFh.
The highest address bytes contain the user reset and interrupt vectors.
Never access memory locations marked as ‘Reserved’. Accessing a reserved area can
have unpredictable effects on the device.
