4.1 Operational Registers
1. R0 (Indirect Address Register)
R0 is not a physically implemented register. It is used as an indirect addressing pointer. Any
instruction using R0 as register actually accesses data pointed by the RAM Select Register (R4).
2. R1 (TCC)
Increased by the instruction cycle clock.
Written and read by program as any other register.
3. R2 (Program Counter) & Stack
R2 and the hardware stacks are 12 bits wide.
The structure is depicted in Fig. 3.
