Register and memory map
As shown in <Blue HT>Figure 4, the MCU is capable of addressing 64K bytes of memories
and I/O registers.
The available memory locations consist of 128 bytes of register locations, up to 384 bytes of
RAM and up to 8 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.
Memory locations marked as ‘reserved’ must never be accessed. Accessing a reserved
area can have unpredictable effects on the device.
