Introduction to RS08
The PAGESEL register defines the memory page to be accessed, the register X indicates the corresponding
location in the paging window that points to the desired upper memory location, CPU access through
register D[X] and the paging window can index to the corresponding upper memory location. Most pseudo
instructions can utilize this scheme to perform index addressing to the upper memory locations.

MCU reset provides a way to restart the MCU to a known set of initial conditions. An MCU reset forces
most control and status registers to their initial values and the program counter (PC) is started from $3FFD.
In the RS08 platform there is no vector lookup mechanism, a JMP instruction (opcode $BC) with a 2-byte
operand must programmed into the locations $3FFD–$3FFF. The operand indicates the user defined
location to start user program execution.

Accessing any unimplemented location through the paging window will
generate an illegal address reset.
